Check out this oreillynet article on how to build a VPN. Whats that to do with Wireless? Palm has a list of VPN Clients for their products here. couple that with a mobile phone and bluetooth, and the ip address of your machine thats acting as a VPN server and you have a VPN you can access from the bus on the way home and check your mail! when my PDA arrives, im getting this software and im testing it out. sounds like a cool idea!
