Thanks Paul, I vaguely remember being told about this effort by my mentor which is what sparked my interest.  At the time we were trying to optimally use all available CPU resources for rendering and while we did have working solutions it required lots of perl and shell.  so the idea of CPU resources being available and shared as a foundational concept on the network was really interesting to me. I also seem to remember him telling me about working on the patriot missile system, although i am not certain if i am remembering correctly that this was something he did at apollo or at another company in the boston area. -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
