If IPSec adds any latency beyond startup negotiation The encryption takes some time. Some $olutions will have hardware for it, but straightforward implementations mean lots of bit-field operations, which most C compilers don't optimize very well, and some compilers on certain platforms

Usage of language does change and meaning does evolve. (has anyone set up a VPN sans encryption recently?) Well, does it count if the encryption doesn't cover the whole path? I'm aware of a number of ipsec "vpn" hardware vendors out there who are looking to put encryption in ISP edge
