Yes, there is such a beast! Well almost!
If you have read my earlier posts you will know that I was looking for a bluetooth to wi-fi retransmitter. Well there doesn’t seem to be such a thing as that but there is a USB/mobile/EVDO thingy that does a similar thing. Cradlepoint technology makes it for about US$180, though the street price seems to be about $40-50 lower.
This seems to be a great solution to using your iPod Touch while on the road!
