To get the XP machine to work as a BT interface to Internet you have to enable internet sharing (on XP) for BT.. won't that work only if you have Admin rights? The internet cafes I've visited didn't have admin rights for the users. I haven't tried the equivialent with a wi-fi dongle, but won't that too need admin rights, somehow? Mind, it would be great if it's possible, I too would like to update mail etc. on the N800 by visiting a cheap internet cafe with the N800 and a BT dongle (or wi-fi dongle, if necessary) in my pocket.
