I thought about that too, but as far as I see with OpenVPN you have the single OpenVPN server as single point of failure and all the traffic goes through the server, which quickly becomes a chokepoint. If I needed this again, I'd try out tinc first. It does not appear to have the single point of failure issue.

We have multiple standby servers to prevent the SPOF issue.
One problem we HAVE seen is a reduction in maximum bandwidth. Since we're CPU limited, however, it hasn't really been an issue.
