I think some HTC phones can do that; I don't think it was very popular, though. It should be possible to do without rooting your phone; I think Koush was discussing a similar proposition (tethering a phone to a tablet) using Android's support for usermode VPN applications. I've no use case for it, though, so you're on your own there :-) It would also not be quite so "plug it in and it works" to set up, since you'd at least manually need to set up NAT.
