Is this true?

[Shreyas Reddy]

For each instance of a remote class, there is an instance of stub class and a skeleton class depending on the vendor

IMHO, yes and no.

There is gonna be always a stub per client (on the client side of the conversation) but the implementation of the skeleton can vary. You may have a skeleton per each stub or vendor can implement one "master" skeleton that will handle all requests. In this case the stub will also send some sort of session information so skeleton can distinquish between different clients.
