As I've been composing a more complete answer that addresses the various
concerns address in this thread (Why is Git different from SVN?  What are
the IP ramifications?  What are the community ramifications? How can we work
to optimize collaboration on open source (or why is social messaging
different from email)?), I've come to the conclusion that (1) it's a bad
thing to try to propose new concepts/practices/process to the ASF and (2)
the ASF's IP policies do not afford the kind of protection that I need in a
core project that I would build a business off.  I will be glad to share my
reasoning about these conclusions off-list... I don't want this to turn into
another flamewar.

I think the best course of action is to ignore my turtles proposal... I'll
focus efforts on the existing ESME code and we can take steps forward (as
opposed to a giant leap) based on what we have now.

Thanks and sorry for the digression.

David
