--------------------------
SRT: To see Howard Foster - who has implemented CDL (albeit not fully); Howard is interested in
a full implementation, but cannot commit to a timeline at present
Yves: Point to http://www.doc.ic.ac.uk/ltsa/bpel4ws/ - Howards Work.
SRT: What he is doing - can take any CDL description, and as long as there's no channel passing,
can load it into a state transition system - checking it for livelocks and deadlocks
- what he is using makes the channel passing aspect complex, which adds to the importance
of pi-calculus; Howard is interested in putting his work into the pi4soa project.
