That would be great if it were fast enough. But we would have to
create multiple objects for every node shown on the screen every time
the user presses a key to move through the structure; the garbage
collection overhead would be impossible.

I've been thinking about this too; perhaps the key is to do the
optimization we discussed when I was in jkl last fall, about having
some system so that we do not need to create different Lob objects for
everything we show on the screen. I'm not sure at all about the
details, though.

I think we should first get this demo ready before starting to work on
that, what do you think?
