Re: OCP transport nomination

While re-use is certainly expected, we shouldn't make the overhead so
high that it becomes impractical to open many connections.  Separate
connections might be needed to keep sensitive user data encrypted
under different keys, multiple connections might be desirable for
scheduling streaming applications, etc.

 No, I don't think you're missing anything. You summarized very nicely 
 what my understanding has been for a while. Since we expect to 
 "re-use" estbalished TCP connections between OPES processor and 
 callout server, the TCP connection establishment overhead is probably 
 not of big importance.
