Best way to sync files?

Question

What is the fastest, most secure way to sync files between remote networks?

My goal is to replace the local "My Documents" folder on our users' laptops with a synchronized "My Documents" folder that is actually the remote server's shared folder.

I could easily accomplish this with Dropbox, however the lack of encryption and a peer-to-peer architecture makes that solution less attractive.

What about a Windows VPN? Any free peer-to-peer applications or Windows built-in solutions?

Answer 1

Using Windows' built-in offline files support along with a VPN is more or less the standard way of doing this I've seen.
