i borrowed the initiator/responder terminology from iSCSI, and it seems 
intuitive to me. this isn't a client/server situation, because a given host 
might be both a client and a server, in a multi-level transfer graph. we need 
terminology that describes the transaction, and not the host or hosts 
participating in that transaction. we stopped using requester/responder when 
the op codes stopped being limited to just QUERY and IQUERY and STATUS. (in 
other words, UPDATE is technically a request, but not notionally so.)

what's your proposal?
