Well, I’m looking to do the same thing basically. I want a VPN connection to a remote server that behaves exactly as a single fast connection even though it will be aggregated over multiple slower 3G modems.
I assume I need one ZeroShell machine at each end, and right now I’m mostly interested in learning from anyone with real world experience from a setup like this. Is it reliable? What happens if one of the modems suddenly experiences a connection problem (high packet loss etc) ?
