Hi I am curious about your use of the term JMS as it relates to messaging in your posting. JMS is purely an API definition and doesn't guarantee service interoperability between different JMS systems, whereas as messaging wire protocols such as AMQP or XMPP do provide levels of interoperability. A number of JMS providers can/may use AMQP or XMPP, JMS over SOAP transport to provide broader interoperability.
It seems you are advocating appengine (java based) adopt JMS api for messaging as well as build an underlying messaging system. Adopting JMS would seem at odds with the the general thrust of appengine. Both in terms of other language support (Python doesn't have JMS. Python can interoperate with various messaging systems using other interfaces based on things like XMPP, AMQP, STOMP etc) If google did such a thing I would imagine JMS api would be a veneer above an XMPP/REST/PROTO-RPC based implementation. Certainly appengine apps can participate with existing messaging systems today (as Brandon has demonstrated) and as documented on the Apache ActiveMQ site. "ActiveMQ provides a bidirectional bridge between ActiveMQ messages and XMPP. if a client joins a chatroom / conference room, the name of the conference room is mapped to a JMS topic of the same name" I have a sneaking suspicion what your really want is a Message Routing Framework like Camel. Because everything else you have asked for is sitting there in appengine land. XMPP has pretty much moved into the Messaging/MOM/EAI/ESB realm to some degree. One last point, in my opinion trying to move away from HTTP as a core low level transport is probably a mistake. Have a read of this article http://spring-java-ee.posterous.com/remote-observer-pattern-with-publish-subcribe as a good counterpoint to what you are thinking about.
