One of the nicest things about tinc is how little attention it needs. It starts on boot, and no matter if the connection between two points drops, or one end gets a new address, or connects via IPv6 instead of IPv4, or restarts, the connection just always comes back up magically, without any futzing. There are many other tunneling methods that don't do this.<p>I used to provide a tunnel using tinc via a MIPS-based Cobalt RaQ. Throughput was surprisingly good, even on an old 250 MHz CPU, so even though I hear people talking about needing something faster, I can't imagine other tunneling methods being measurably faster, unless they're using weaker encryption. I'd benchmark it some time, but the slowest NanoPis that I use for tunnels these days can push many times more traffic through tinc than their Internet connections will allow. I'd be curious to see anyone else's comparisons, though.
