Sounds to me like a hardware version of the "Grid" style of QNX, where all networked QNX machines pool their CPU and resources to handle all requests across the network (So, say, a single webserver can use other machines on the network to handle the "Slashdot effect"). Oh, but QNX runs with x86's -- Robert "Anaerin" Johnston _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
