I had a returned thought on the issue of whether or not data had to complete the loop between the OPES processor and the callout server. If the proxied protocol is a store-and-forward type, like SMTP, then it seems that the callout server might, quite properly, send transformed messages directly to an application endpoint (SMTP server) without going back through the OPES processor.
If that is the case, why would you need a callout protocol in the first place? Why wouldn't "OPES processor" and "callout server" talk SMTP between each other? "OPES processor" and "callout server" would just be two mail servers talking SMTP...
