Even the cheaper are quickly shipping with GigE as standard. In fact, the next Southbridge revisions all incorporate GigE (also decoupled from PCI BUS, so you can actually do something besides pushing data over the LAN). >>Some initial attempts at estimating >>communication & compute demands would >>be in order.

Did you release FREP? If so, were? Best regards, Gabriel
