I recall a presentation from folks from Empress Software
<http://www.empress.com/> back in about '94 or '95 offering this very
feature as part of the "base functionality" of their product.

I'm not sure it's quite fair to assess things as "more or less
preposterous" simply because they prove ludicrously expensive to
develop on a particular platform that happens to be targeted by even
more ludicrous quantities of development dollars...

On the other hand, it seems unlikely that "improved performance" would
be one of the merits of this approach...
