I think we need to make sure the appropriate hook's are in place so it
can be added, but beyond that I see an explosion of variations and
dependencies.

My initial impression, like yours, is that it can be accomplished in a
custom scheduler.  But I'm not a trusted computing expert, so I'd be
interested in hearing why that wouldn't work, and what additional
hooks might be needed.
