Several VPN tunnels are available for anonymity. But they are all bandwidth-limited, and some are unreliable. Let's say they are accessible through interfaces eth0, eth1, eth2, ... 1. How can a linux box be set up to use all these VPN tunnels simultaneously in order to increase bandwidth for browsing? 2. Is it possible to add redundancy so data is transferred in duplicates through interfaces eth0 and eth1 say? 3. Is it possible that an rsh session goes through all VPN tunnels, as in 1 and 2 above?
