I expect to begin discussion of how that might be achieved in a few
days. I understand the starting place for your thinking, but am not
deterred because I see some solutions. I feel certain you will point out
some difficulties, but I think it is worth doing. Please lets start
those discussions from a neutral point. If you find a real showstopper,
then so be it. Sorry for the delay.
Bruce was asking about why I might want that. If we can at least agree
there is a use case then it helps.
