Thanks, John.  I'm not using PSTricks, but I am using textpos to place
blocks of text anywhere on the page.  I don't know what the overhead of that
is.  I'm also looking at using flowfram for similar reasons, so it would be
worth my time to compare the costs.

Ultimately, I'd love to do this all in plain TeX, but I just don't know
enough to do that.  Hopefully in a future version ...
