	Based on talking to an NCUBE salesman at the Oak Ridge Hypercube
Conference last September, you can't get enough memory on one of their
nodes (128K, I think) to do the sorts of things I want. Does anyone know 
if this will change? 4 Mb/node seems like a reasonable number to me.
	Other than this major problem I was very impressed by the NCUBE.
Obviously some people can get good use out of them. But commerical 
applications != Mandelbrot sets!
