I'm running one on my webplayer now.
I am using WindowsME on webplayer, Windows98 on PC with AnalogX's proxy.
I do not recommend Intel's connection sharing software, I had quite a bit of instability with it. Configure both machines with static addresses, if you don't, you'll run into problems finding the proxy. Did not look into it, but using the Intel software to set up the adapters does not configure an address, so it's up to the Windows98 and up hokey self DHCP thing - hate it. Just configure static addresses, it will work out alot better.
Have not done a great deal of anything other than web browsing, works fine for this. I'll probably try and do some MP3 streaming once I work out a way to bridge or route the connection over to my other network at home. As it is, I can only map drives to the Windows98 machine that has the Anypoint. Everything else is on the Ethernet lan. I've got one the the Proxim HomeRF gateways on the way, I hope that I can dumb down the device to only bridge or route, I don't need it to do the Internet sharing (NAT).
Haven't yet got it to do a successful suspend/resume using the front button, kind of gave up on it and just turned on the blank screen saver, though I would prefer the button, as the screensaver does not shut off the florescent in the display.
If anyone has worked out how to get this adapter to suspend/resume reliably, I would appreciate word on this. Experience with using different vendor HomeRF would be helpfull, especially Intel Anypoint to Proxim HRF Gateway.
