I'll give it a try!

don't be shy! I'm always checkin in untested and suspicious code ;-)

The last thing I did, was building a ServerConsole that can be used for 
remote administration of a OJB server. But I did not work on the 
internals for quite some time.

AFAIK most people are using the singlevm mode only. For most scenarios 
this will be sufficient.

Mhh, I once removed all references to DescriptorRepository from 
PersistenceBroker client. AFAIK there is no reading of the repository on 
the client side. That's why I introduced methods like 
getDescriptorFor(Class c) into the PB interface!

If the repository *is* parsed on the client it is a bug !!!

feel free to discuss any further issues regarding c/s mode directly with me.
