here's the idea we had in mind: create a SLSB that takes commands and then these commands are executed within a JbpmContext that is created in the SLSB. a set of predefined commands include TokenSignalCommand, TaskInstanceEnd command, ... then the SLSB would be exposed over a webservice. don't know yet how that would look like. especially how the commands themselves would be mapped. with JAXB ? there are versions of the SLSB and the commands in HEAD of cvs. please, take a look there and comment on them. as we would like to make this a collaborative effort and make sure that as much requirements as possible are met with our design.
