Regarding the NANOG meeting. I am not endorsing their product (or saying anything against it, for that matter, just neutral), but we do have two Xircom wireless Ethernet access points. There are for short distance (may be 30 meters or so in my experience) communication and do some 1 Mbps with a 2.4GHz spread spectrum radio as some "shared medium." The radio guts sits on a PCMCIA card. that fits nicely into a (laptop) PC, and costs a few hundred dollars (not sure about the exact amount). If there were sufficient interest, we could probably use them at the meeting place, so don't leave home without your PCMCIA card. Though I will only install the access points if people ask for it. Y'know, people who don't always want to depend on cables. By the way, I would also be interested hearing from people having experience with other wireless products.
