Hmm, do you want to connect to sessions on a remote machine (e.g., 
access things on your home system when away from home?) or have things 
running locally on your mobile computer?  If the latter I think I'd 
need to learn more about what you're doing.  If it's the former, 
here's what I've done:

I use VNC running on systems at home for such sessions, so I can start 
a session and then can access those things (xterms, web browsers, 
etc.) from anywhere I can get a network connection.  When away from my 
home LAN I can set up a VPN connection via OpenVPN and even if I 
hibernate my machine when I bring it back up the connection to VNC is
