Whose development cycle? Yours or theirs? How are you going to stop either?

But it doesn't need to be so. See my earlier post to Andrea.

What's wrong with ejb-refs? With either ejb-refs or CMR you're going to need the
interfaces of the components you're using. Any change to those interfaces (both
syntax and semantics) will cause you to recompile your component.

Actually, reducing coupling between components will increase the reusability of
third party components. This will lead to broader markets, increasing sales, and
more R&D.

No. Just not experienced in building component systems yet.
