Being able to produce and consume log messages over JMS is a neat feature that could be fleshed out a bit more. One step toward accomplishing that would be to add more MOM protocols. AMQP is one of the leading standards for cross-platform messaging, and the Qpid project provides some nice libraries for working with AMQP in general. See the Qpid Proton project for more details on that.
I'd like to take this feature as a way to make the JMS appenders and JMS receivers (i.e., LogEventListeners) a bit more messaging agnostic. It can also pave the way toward supporting a couple other common messaging protocols that could be useful (like MQTT and STOMP).
Ideally, I'd like to have this feature without any Spring libraries as this is not a very advanced messaging application feature.
