Do we expect the set of callout servers to change so rapidly that server connections cannot be reused at the OPES processor? If yes, we may have to support UDP-like OCP transport (and probably change a lot of OCP requirements related to "OCP connections"). If no, then transport connection setup time is not an issue and TCP-based OCP transport should work as well (or better) as UDP-based one. I think the latter is much closer to reality. Am I missing something important here?
