Like I said, I've never set up a network with a private AS before, the only ones I've set up had their own public AS number. So I'm unsure as to how confederations and such fit into this, but from the sound of it, it seems like a confederation is simply like an OSPF area. In any case, I think we are jumping ahead of ourselves by discussing BGP and all that. We don't even have a base network to play around with yet, the conversation just went the way it did for who knows what reason. My problem is, I live in brooklyn park, and I have lots of tall trees, so to set up a link with anyone else I'm going to have to get a nice tall mast and hope the city doesn't come over and break my knees for violating some ordinance. I have a friend in North Minneapolis though that would likely be willing to let me put up an antenna at his place, and he works for a local ISP also, so it's possible that they might be interested in putting an antenna on their roof (near Surdyk's). I'd like to put one on the roof of where I work, but out building people barely let us put our satellite feeds up there. If anyone is planning on doing this, are you looking at 802.11b, a, or that motorola canopy stuff? 802.11b is 1/5 the speed of 802.11a, and 802.11a isn't too much more expensive. Wouldn't it make sense to use a faster technology?
