Talking about John Paul Cook : Using Wireless with Hyper-V
This looks promising for my dev setup. Tried the ICS (Internet Sharing to no avail). I was getting ready to install a proxy server (the ForeFront Threat Management Gateway), but this looks like it might be an easier configuration to maintain (when at a client location). Once I get Hyper-V networking with the outside, I might double back and explore TMG too.
