--------------------------------------------------------------
Looks like a perfect case for correlated process instances - meaning that you can \
assign business key to process instances that later on can be used to get hold of \
process instance. That will come in with version 6.0. And in meantime...

option 1 has an issue if you consider to use persistence (and I assume you do as \
there are long running processes). The issue is you cannot simply query for processes \
in that session as process instance resides in ksession only when it is being \
currently executed/processed by the engine. As soon as it reaches a safe state it is \
persisted and removed from ksession to save memory, etc

Option 2 is one way to go and you can easily create processes from rules and as you \
said you need to make sure you retract fact when process completes.
