DSL sucks. While they may give you QOS at the IP level, the underlying ATM 
and/or Frame Networks will still suffer from overcongestion and will have 
no idea of the TOS bits set at the IP level riding below them.

All that being said, we have a 100 meg hand-off to X/O's backbone, and a 
client that insisted on doing 6 lines through a 1.54 meg SDSL connection 
through X/O. We initially refused to do the project, but after a 
traceroute revelead they were 2 hops away (Our router, DSL router) w/ an 
average latency of about 16ms, we decided to give it a try. So far, so 
good, but the minute their DSL takes a dump, we have a plan in place to 
route all their calls to their Cell Phones. So far, that hasn't happened, 
but I'm expecting it any minute now. ;)
