I was meaning for a network really. It's a lot easier by shuffling connections or for failover. For a single connection, Udp might? work alright, otherwise you'd need to do some connection tracking such as timeouts or bandwidth etc, maybe tunneling to a proxy or through a dns server (but that's just wrong, not to mention out of your control). I'm sure that magic will be around somewhere, I've read something about it, if I ever look into it. I can let you know. Roundrobin would probably be easy enough, but it wouldn't be optimal and isn't 3g going to be expensive (not to mention the latency) for anything other than when necessary, such as for failover anyway?
