Mine is going to be equally random, just much shorter :) I'll try to 
think a bit more about this later.

Like with dnotify, I think that the grouping and manageability of
changes coming through a magic FS is going to suffer. And I think
that this is one of the cardinal weak points in CVS, and thusly
one where we should aim for being strong.

But I have no good ideas on how to handle this and still get
transparency.
