As far as I know, no final decision was taken regarding the name of the new JMS implementation.

Runners up are:

* JBossMQ
* JBossMessaging
* JBossJMS (not acceptable on reasons related to trademark)
and unoficially JBossMess, which I don't think it will make it, even all of use love it.

I could think of several more:

* JBossMS (JBoss Message Server)
* JBossMP (JBoss Message Provider)
* Aggregate (don't ask me to explanin the thought process that led me to this one, all I can say that it was inspired by the serverless part of the implementation).
* M-JBoss

My vote is for JBossMS, we closely circumvent the forbidden JBossJMS.
Please voice your opinion.
