Of course, a BPEL engine can send such initiating messages, not such 
partners. This gives us all the flexibility we need within BPEL to 
create scheduler applications of many types.

Self-scheduling processes are in general a bad thing. Scheduling is a 
separate concern from the process logic itself. The fact that one must 
alter the process definition in order to alter the scheduling policy is 
indicative of inappropriate coupling between the two. I suggest that we 
not burden BPEL with features that encourage poor practices.
