I bet it will be quite hard ;-)

For now, I would be happy if we could agree on a membership API.

what this mailing list is intended for.

Will you - or someone else from Compaq's effort - be at Ottawa Linux
Symposium's clustering working group?

Hierarchial clusters are hard enough, being a member of two clusters at once
is an interesting problem - what possible advantages do you see here?
