Okay. So now we are getting somewhere :-)). So... The Inquiry needs to be abstracted using SOAP. The Updates will be thru the Admin Console and wouldn't need abstraction. The Service Security is for the ESB has a whole and we will need to work it out together. Next thing that I can think of is the Distributed nature of the Registry. Clustered Registry I should say.
