We want to navigate a 3D image cube, looking at all
three slice orientations, zoom, pan, draw ROIs, sing
and dance, all the usual things. And, of course, the
client wants it all faster than we can do it now in
IDL. :-)

I was looking at the ION Java Human Browser Demo,
which seemed a less powerful example of what we would
like to build.

This is still on our To-Do list, but it's coming. :-(

Well, I'm naive enough (and don't know enough about Java, probably)
to think this would be a Good Thing. Why is it a problem?

Yeah, I think interactivity is critical. We can do without some
of the bells and whistles, I guess. But navigating images quickly
and being able to annotate them is essential.
Thanks for the info.
