I certainly could take a stab at it. It would be nice to get a
"doesn't sound like a terrible idea at first glance" from Jakub (and
anyone else) before starting on it. Maybe someone has brought this up
before and was shot down for $reason. If so that would be nice to
know. Of course it's possible I could also find some reason it won't
work after investigating/implementing/testing.
