I've been thinking about just this problem recently, and am likely to
modify nnvirtual to allow these sorts of things more easily/efficiently.
The poor man's way of doing some of it now is to have a big nnvirtual
group and using limiting to narrow things down.

I've also been thinking of adding "labels" which are sortof like more
generalized marks, ala gmail, and mixing that with nnvirtual also.

If people have nnvirtual ideas, now is a good time to mention them.

On my nnvirtual thought list:

1. combined nnvirtual with initial limit setting.
2. nnvirtual for `nnmail-split-history'
3. combined nnvirtual with various user pre-select functions
   (probably how 1&2 actually get done)
4. labels
5. redecide which marks copy and don't copy into and outof virtual
   groups back to the base groups, since new marks have been added
   since nnvirtual was last really touched.
