Depending on how you design the object schema you can register notification requests with a Paos server to notify you of any changes as well as any additions/removals. Notification requests have the same power as regular queries. So all you need to do is to define the catalog of objects that may change as a query and register it with Paos. Additions/removals are handled by formulating queries for changes in sets of objects. * * * I'm currently in a paper deadline crunch - sorry - but I'm working on the Paos documentation/tutorial "real soon now". :) Carlos
