The transmission lines are already operating at capacity, all the extra power transmitted to and from the plug-ins would require significant and costly infrastructure upgrades. As it is, we're only planning on "smart" transmission lines where sensors allow us to increase capacity by reducing the safety margins on those lines. Whether to buy or sell to the grid can't be a purely consumer decision when we're this close to the grid's maximum capacity. The infrastructure is also designed for power distribution from central generation sites and hence have higher capacity lines the closer you are to the generation site and smaller cheaper lines the further away you are. Also the breakers are more sensitive the further away you are and break at higher current levels the closer in you are. The plug-ins would represent distributed co-generation and much of the grid simply would not have the capacity required. Basically two thirds of the existing transmission lines would need to be replaced to do what you are proposing. For a modest city, that could easily be in the tens to hundreds of billion dollars, that would be an unheard of national infrastructure expensive many times the current trillion dollar economic stimulus plans.
