I'll second that.  I tried to do roughly what was described above (NFS
over a VPN across the Internet), and the performance was absolutely
abysmal.  After doing a lot of searching on the Internet, it appears
that just about everyone else's performance is too.  

Surprisingly, what _does_ work quite well is simply sharing resources
using samba.  Mounting a samba share across the VPN across the Internet
is remarkably responsive. 
(and it's all encrypted to boot).
