Plenty of ideas. None implemented.

1. Some kind of load balancing NAT device. Can be used in a more general
way moving any kind of traffic to the cheap 128k link until saturated.

2. A deamon that plays with the routing entries based on network load.
If 128k link not saturated then use a default route that causes the
Squid machine to use the appropriate address, and if this is saturated
then change the routing table to use the other address.

3. Similar to 2 but coded in Squid.

4. Probably several other options.
