I see what you're getting at ... I don't know if REST would say anything one
way or the other about this, after all it is just HTTP best practice not
anything you can't do today.

Well, I've learned the hard way that if you ask Fabian Pascal this question,
he will rudely question your intelligence, education, experience, 
... parentage, species <grin> ... but not offer a compelling answer.

For what it is worth, there is supposedly a "stealth"
company with a patent on a truly innovative database technology that
will do all this with the assistance/blessing of Codd and Date.  The
only trace of them I've found on the internet is this help wanted ad:
http://www.cppsig.org/guestbook/ [search for "Codd" within the page],
and US Patent 6,009,432
