If anyone is interested in experimenting, I'll be happy to provide the code
that you can toggle alpha sorting. Ive never done a performace comparison,
but seeing as you guys have something implemented that can excersise it,
it might be worth your while to

David,
Very cool ... it would be nice if we could hide the fade in of the
objects a bit better, but I'm not sure if there is an easy way to do
that. Vega/performer supports something called fade level of detail
which uses alpha to fade in the object (or fade between levels of
detail.) But even
