Hi Eric,

in my opinion, there are more complex things in org-mode already ;-)

I agree, that such functionality doesn't need to be provided in org
itself.
Thanks a lot for the pointers to possible entry-points for an
implementation.  I hope, I'll find time to to go for it.  Would be good
for my elisp, anyway...

Regards,
Andreas
