I have very good results with 2 Belkin F5D7230-4 routers. You can set them up so access is restricted to specified MAC addresses. A couple years back these were FAR, looks like they retail for approx $40 at Belkin.com. I was only running a p3-600 with 256 mb ram- was using it as a digital picture frame (and soon, hopefully, a print server) pulling images I loaded onto the core. If streaming video I would guess, as Zaerc said, the bandwidth is just not there...
