Ah, the good old days of 2001 when Linksys WAP11 wireless boxes cost  
a mere $250 :-)

What he doesn't mention is a lot of phone companies now make sure a  
"alarm circuit" now has inductors stuck in the circuit so it won't  
work above audio frequencies. Bye, bye DSL. YMMV.

But if anyone is doing this with Qwest I'd like to know (or any other  
phone company come to that). I would seem to be a good way to connect  
up the discontiguous Seattle Wireless network.
