Hi Paul
You can do this on a linux box with a pretty much basic kernel.
I currently have a similar setup at home with a DSL and a cable line =
(from different providers).
Here's the script I'm actually using: =

Some packets are tagged with iptables (SSH as an example) because I want =
it to prefer the DSL connection. You can do pretty interesting things =
with it, even per-packet round-robin distribution =85 which is a Bad =
Idea=99 though.
If you want it to fail-over automatically you need to patch the kernel =
etc. You'll find all information on http://lartc.org/ (especially on =
http://lartc.org/howto/lartc.rpdb.multiple-links.html) and here: =

This setup is running for about a year now and it does this quite well.
