They are different providers.
DSL 1 is 384k/1.5m adsl at pacbell
dsl2 is 768k sdsl landmark (lmki)

What do t1 and t3 customers do? Is the only criteria for "feasibility" a
need for more IPs?

I could get a second link to pacbell, but sometimes their entire network
gets unstable, and I would still need a second provider. Doing the same
with the other provider would require four links, and still wouldn't fix the
problem if one ISP crashing completely.

Hmm, I wonder how exactly this would work with the 6BONE. Can you get
traffic from ipv4 into the 6BONE from the "normal" internet? How would I be
addressed?
I probably wouldn't choose my ISP then, I'd choose a company that connects
to several ISPs, and that'll be more expensive. :(
