Virtual Access Point Software

Hi,

a Mobile Apps version of a Virtual Access Point using a laptop with a network & a wireless connection available.

Just wondering if it has been discussed at all - can't find any mention of it in a Search. There are programs out there which make use the windows 7 feature but the computers I have access to all run WinXP.

I work all over the world for weeks at a time in places without WiFi and would really like to be able to connect my iPod Touch to the outside world. A bit selfish I know!

thanks in advance

H
