Nissan announced at CES that they're going to enable to Vehicle to Grid charging (potentially getting paid for both giving and receiving power from the grid).
Has anyone ever used this or something like this before? Is it actually feasible?
And if it does exist in the near future, what does everyone think are the pros and cons?
The benefits are obvious, and IMO, in a decade or two it will be viewed as comical that in the early days of the BEV transition we put hundreds of millions of kWh in vehicle battery packs, then limited their use by not
providing them the ability to discharge to, as well as charge from, external sources.
Links to many many (V2H), vehicle-to-building (V2B), and vehicle-to-grid (V2G) applications are discussed on this thread:

...Announcing the New Nissan LEAF: The Next Chapter in Nissan Intelligent Power
On stage at CES, Ghosn announced plans to launch a new Nissan LEAF, with ProPILOT technology, enabling autonomous drive functionality for single-lane highway driving. The new LEAF is coming in the near future and represents the next chapter of Nissan Intelligent Power.
The new LEAF will build on Nissan's industry-leading position in electric vehicles (EVs)...
EV batteries can do more than just provide power for driving – they can also be used as energy storage devices. To this end, Nissan is promoting EVs as clean mobile energy units. Integration of EVs into society will help energy distribution across the grid, and vehicle-to-home (V2H), vehicle-to-building (V2B), and vehicle-to-grid (V2G) solutions have already been adopted in many markets such as Europe, the U.S. and Japan.
In 2012, Nissan introduced its "LEAF to Home" system in Japan, allowing drivers to supply a house with the energy stored in a Nissan LEAF battery. Users can charge the Nissan LEAFs at night when electricity is cheaper, and then use that electricity as the daytime power source for a household. This way, the system helps to alleviate power consumption during peak periods when demand is highest and most expensive. It can also be used as a backup power supply for blackouts and emergencies.
Nissan has also been testing a V2B system at the Nissan Advanced Technology Center in Japan since 2013. In this project, six LEAFs contribute to a decrease in electricity costs. Nissan's new Europe HQ in Paris will be partly powered by V2B and V2G technology when it opens in spring 2017.
Today about 4,000 households in Japan are utilizing EVs to manage home energy use, and thousands of EVs are powering buildings in the U.S., Japan and Europe.
For example the Hawaiian island of Maui, Nissan LEAF owners volunteered to participate in a unique project which explored the possibilities of combining smart grid, renewable energy and electric vehicle technologies into a single comprehensive energy-management solution. Residents use renewable energy from wind and solar sources to power their vehicles. In return, they use energy stored in their EV to manage the energy of the island. About 600 LEAF owners participated in the project and Nissan, along with other partners, are using the information to inform technology development and policy recommendations.
Elsewhere in the U.S., Nissan is involved with a variety of V2G and V2B activities. For example, Nissan has been a long-term partner with the Department of Defense on multiple grid-based projects at Los Angeles Air Force Base (California), Fort Hood (Texas), and Joint Base Andrews (Maryland). Combined, approximately 30 LEAFs have been deployed at these bases to demonstrate the technical and market viability of EV participation on the grid. Similar programs are underway between Nissan and other organizations around the U.S., including universities and utilities.
Nissan is also involved with commercializing V2H technology in the US based on market success in Japan. In this context, V2H would provide a homeowner with emergency power during outages and, potentially, a means of storing solar energy for use later in the day or at night. As part of its commercialization effort, Nissan demonstrated the V2H technology to a variety of US audiences in 2016, including to the general public.
Finally, Nissan is also helping to extend the "second life" of the EVs' lithium-ion batteries. In Europe, through the xStorage project, in partnership with Eaton, consumers can save money by drawing energy from the sun and the grid, and then sell it back to energy companies. Meanwhile, xStorage for business allows organizations with high energy consumption to manage their energy usage and to power their business in a more sustainable, smarter way.
For example, in November 2016, Nissan and Eaton announced a ground-breaking 10-year deal with Amsterdam Arena – the world-famous entertainment venue and home of Ajax Football Club - to provide back-up power from secondhand Nissan LEAF batteries. The xStorage-building system will help to ensure the lights never go out at the renowned 55,000-seat stadium, which has played host to numerous high profile concerts and sporting events over the years...
