Ok, that makes sense. I suppose the only issue might be that the recieving computer on B's side would have to be running full time to keep ICS running, no? And yes, they do have great LOS- I figure that a 5-8 db antenna should do the trick. The base AP is a senao NL-3054CB3 long range. A bit on the high side cost wise, but really powerful.
Forgot to mention-B has an in-home wireless network, so I guess they would have to have their wireless router plugged into their switch?
(I'm getting paid well for this) lol
