I use a T1/26xx for primary and a sprint datacard in a little NAT router for secondary. The two boxes sit on the same LAN but provide different gateway IP addresses. The sprint router does the DHCP, so things that ask for DHCP wind up using that as the primary. Some boxes use the 26xx as default gateway with static IP's outside the DHCP range. A smart enough box could choose paths per conversation by playing with the next hop. If that active path for a box fails I can just change it's default gateway to switch to the other service. I have a routable C I use for the LAN, the sprint connections just NAT's it anyway, the other connection is firewalled but not NAT'd. Seems to work ok for me. Could be made fancier.

The DSL provider would have to support that capability. I also recommendsomethinglike a Cisco 2691 router with two WIC-1ADSL cards.
