Blackberry VPN for 5810/6710 ?

[tehilton]

Is anyone aware if RIM or some third party is developing or has developed a wireless VPN for the Blackberry 5810/6710 ? I know there are VPNs for the Palm and PocketPC OSs. (movianVPN offered by Certicom for Palm/PocketPC OSs; Mergic VPN for Palm OS)

Thanks for any help.

What i really want someone to do is use a Berry device (58/6710) wireless connectivity, have the ability to attach it from it's serial port to a PC's serial port for a slow but usefull gateway to the net. I think XP can use serial PPP connections. wouldn't that be great?
