While I'd extract the socket code from an earlier project for reuse, it always needed to be modified a bit to get integrated into the new one. It just gets tedious after awhile. So adopting a more abstract, pre-existing transport protocol just eliminated the need to deal with that.

Nope, ZeroMQ is essentially just a transport layer, which is all the functionality I wanted of it, so that I could stop having to mess around with sockets.

TOMI_4_Ada essentially arose out of my desire to have a simple, consistent Ada library for text-oriented message interfaces. My projects rarely have any need for extensive or high performance protocols, so a nice clean set of client/server and topic-supportive publish/subscribe services meets my needs.
