 Not without a vast amounts of infrastructure coding.  You're
 basically talking about what Oracle has spent the last 3 years and
 $100 million working on.

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...

Rules of the  Evil Overlord #92.  If I  ever talk to  the hero on the
phone, I  will  not taunt him.  Instead  I  will  say that  his dogged
perseverance has given me new insight on the futility  of my evil ways
and that if he leaves me alone for a few months of quiet contemplation
I will   likely  return to  the  path  of righteousness.   (Heroes are
incredibly gullible in this regard.) http://www.eviloverlord.com/

Would be nice, though.
