I have been involved in the petri-pi work since it's inception. I think Nik Kavantzas (Oracle) has also been involved since the early days. I certainly concur with BPEL being but a part of the puzzle. On the theory side there has been much progress on the formal description of WS-CDL and I do expect this work to reach the eyes of the public in very short order. There should be a formal description of WS-CDL based on what is called a "global calculus" and an "end-point calculus" for the projected roles/participants. This will enable advanced type systems to be created that will allow us to type check for liveness properties and also bi-simulations (when two behaviors are the same).
Look out on the W3C choreography lists. The open source offering in this domain from my own company (www.pi4tech.com) can be found at www.pi4soa.org. Note the domain name. The idea is to provide a formal description of SOA-based systems and then generate the services to any infrastructure. Thus one should, in theory, be able to generate a solution described in WS-CDL to WS-BPEL using SOAP over HTTP to communicate. Or generate to Java in an ESB environment or even Java over Jini/Javaspaces. It's not all done yet but it is usable. I've created some pretty big examples already and we are looking at generating to JBI implementation, mule (open source ESB) and PXE (open source BPEL) as a starter. I'd be interested in getting feedback from any interested parties. The plan is to keep it open source forever and for pi4tech to earn consulting and support revenue. Forgive what appears to be a plug. It's free and available and targetted to SOA builders so it makes sense to let you folks know about it.
