Is there something like a general introduction like the developing-with-avalon.pdf? Or could I build one from the current CVS?

(The protocol is something like VJP (which does not really exist at the moment), I would like to build VJPDaemon, which would use this protocol over IP and would launch/start/execute one or more VJPlet. This one I would develop a sar (What dows this stand for?) It would be good to be able to register new such VJPlets or exchange them at runtime. As this is something that tomcat does I thought maybe there is already some component which would do such things.

Thank you very much again. I will have a deeper look into phoenix and the demos.
