I have a laptop and a desktop I want to keep files up-to-date on both of them. I was thinking of creating a hard drive on 'server' and then changing "my documents" to that server path. It should work all right when there are two computers but what if a laptop uses wireless access at my house and more importantly, when it's connected wirelessly on a different IP range when I'm at college?

For the second case, I guess, creating a VPN/remote server connection to the desktop will work, but if I want to make it automatic (my documents mapping), is there way to do that?
