Your interpretation completely wrong.  I was just saying that it is
not a requirement to code everything to the lowest level API that I am
proposing, and giving the Topspin stack as an example of how my design
would be used.  Remember, we are building a "stack" so it makes sense
to layer things.

In any case you are pushing not just Voltaire's design but Voltaire's
code as well so this is a ridiculous complaint coming from you.

What do you mean?  I've come up with several use cases and your
response is always that you'll add yet another special case to the
API.

For example, I suggested being able to snoop every MAD.  I could also
imagine someone wanting to snoop every CM MAD or every SA MAD for
debugging those components.  The restriction of one consumer per class
doesn't look right to me either -- there could be multiple network
management applications all trying to use PM.  I could go on but I
don't think it's worth it.

I just want to provide mechanism and not policy.
