I've been looking for a way to encrypt the connections between my embedded units and my server. From what I understood about openvpn, the server starts to give problems beyond 1024 "concurrent sessions" .... I'm looking at a design that can handle 4K concurrent sessions....although it'll take a few years to get that big.
Use "ulimit -n".
Also be aware of memory requirements for large number of concurrent connections: http://www.stunnel.org/?page=perf
