How would I go about setting up four 3G (I'll use this as a shorthand for GPRS/EDGE/HSPA etc.) modems, each one for a different network, on my machine so that if my first choice network gives bad throughput or goes down, my internet connection will move to my second choice, until I give up and look for a coffee shop with wifi?

Ideally I'd like to eventually package this set up up into a wireless access point outside of the machine, so 'bonus points' for telling me where to ask about such a more technical development of this concept.

Rather than worry about the fact they are Wireless, you just need to research redundant network failover. Examples of the many solutions and articles available.

The basic answer: you need a router, whether manually configured or bought as a one-stop-solution, that can route traffic out over two or more completely disparate networks. There are linux distros that can do this (so for a large time investment you can save money), as well as pre-built solutions. Most pre-builts only support two connections though, so for supporting four you may need to go the custom route.
