no. the usb modem adapters only work on macintosh computers
and they don't seem to function on 10.6 either. (mine stopped working when I upgraded)
I find it amazing that they're charging 5k per house, it should be more like 5k to get to the development, and another $100 per house from there.
OR if you're all close enough, pay the 5k to get SOMEONE (you?) service, and then stick up a hotspot for your neighbors. If someone has a tall thing, like a grain silo or disused windmill or just a really tall house on a hill, do them instead. Put up an omni there. Then get everyone one of those directional units from ebay. They work good and claim up to 21-24db gain, good enough for any line of sight usually. (2 miles minimum to an omni) If everyone chips in that wouldn't be more than $250 per house counting service plus everyone's hardware. I got my 24db unit for about $130 iirc.
It's a project for sure, but worth it.
