I don't think that this maps well to TCP.  Apps need to listen on different 
ports.

Having a reserved bit in the REQ indicate the presence of IP addressing
information (including source and destination port numbers) in the private data
seems most flexible to me.

How would a reserved bit help here? How does the CM know which app to give the request to?

My preference is to use the service ID, with a mapping that looks like:

(OPENIB_OUI << 48) + port number

because that makes my job easier.  :)
