[rabbitmq-discuss] STOMP plugin problems (was: Claim on new ocamlmq broker...)

[Alexis Richardson]

En passant:

STOMP fans who wish to help make STOMP 1.1 and 2.0 may wish to observe
or join the conversation at stomp-spec.  This list came back to life
recently - and now is a good time to state your requirements for STOMP
'going forward'.
