many instances of Shark in one VM

Hi Sasa and others,

      Is it possible to have many instances of Shark in a single Java VM
or in JBoss? We are currently running one instance of Shark as a POJO
library with session bean wrappers in JBoss. 

      We are looking at providing BPM(using Shark) as a hosted service
to some of our clients. We'd like to have a different instance of Shark
(ie. one Shark and database instance per client) for security reasons
and also to separate the repositories etc. for each client. Running a
separate JVM/JBoss for each instance may be too expensive and not
scalable(?). 

     Shark does not allow you to configure more than one instance at a
time ('Trying to configure shark instance that is already configured
!!!'). Is there a way to start multiple instances, each with its own
configuration(ie. different Shark.conf)? In org.enhydra.shark.Shark, we
could make some changes to enable multiple instances, but it seems that
such a change would also have to be made in other classes such as
SharkEngineManager etc. 
	Clustering is also another concern for such a system.

     Tips and suggestions are welcome from everyone.

Thanks,
Roshan Nair
