don't know if that's possible, but how hard would it be to optionally
limit the size of the cube? I have something in mind like only
allowing 64 colors or whatever to be able to start other applications
(and leaving them some room in the colormap) after R has started.

Netscape.maxImageColors worked always fine for me ...
