This is precisely what Kal's PSIs do.
There is a difference, though, because the way I am currently doing it,
the virtual hierarchies are created separately from the topic map, so
there are no PSIs or other associations involved. Naturally this means
no interchange, but where the virtual hierarchies are ad-hoc or
informal, that is often OK.
