Balbir,

This all seems like a little bit too much hand waving to me.  I don't
really see a single concrete user in the "potential applications" here.
I really don't understand why you're pushing this so hard if you don't
have anyone to actually use it.

I just don't see anyone that *needs* it.  There's a lot of "it would be
nice", but no "needs".
