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
