Hey Sylvain,

Sorry, sounds like we had a bit of a misunderstanding.  George did
some research on prospective architectures around this functionality,
but we have not committed to or engaged upon any work on it at this
time.  I did mention that George might have some new perspective on
any submitted implementation or continued discussion due to some of
the information he gained during his research though :-)

Best wishes, and sorry about any confusion in our conversation.
