Can I use my wallet on different computers? I'm used to synchronize my data on different machines. Depending on the data I use SVN, Dropbox or SSH (Unison). Is this possible with the bitcoin wallet, too?
It is, with three provisos.


Never run the same wallet on more than one computer at a time.
Never run an older copy of a wallet when a newer version exists. If you send any funds, make sure to keep the newer copy of the wallet.
Make sure all client programs are linked to the same version of BerkeleyDB.


Overall, I think it's just not a good idea. The client software wasn't designed to cleanly handle the many things that can go wrong.
