It would be interesting to try, but one of the things that makes Freecycle work is that it's organised on a local level. So people are able to physically drop off or pick up items without having to go too far.
Having said that I did pass on a book a couple of years ago to someone on the board, I thought he was more in need of it than I, so it might just work!
