I thought of that but the people at this apartment are cheap. :( I was going
to charge them 10$ a month X 20 to cover the cost of the access and to
recover the cost of the wireless equipment.  If they pay more I will up
their rate.  Our eventual goal is get them on their own dsl modem.

I hear a lot about the buzzword CBQ.  What do I if I wish to follow the CBQ
route?  Do I have to re-compile my stock Redhat 7.2 kernel?  Everything
looks like it is a module when it comes to QOS in this kernel.  QOS is all
new to me but Linux and routing isn't. :)  Tomorrow I am going to re-read
the sections on both sites again.

When we first did the link we didn't get that good transfer rates 64-128 k,
he slapped another 2000$ for some Amps now we are getting about 6 meg link
reliably.  The ADSL I am getting 3 megs down 512 k up.
