For small file transfer between nodes, performance may be a wash,
with EtherNet 1000baseT being easier to implement and more cost
effective in some cases. However, the bulk file transfer rates for
very large files via FireWire 400 (1394a) is significantly faster
than 1000baseT and FireWire 800 (1394b) is more than 240% faster that

For consideration: Alias' Maya CGI graphics rendering & 3D modeling
software on multiple FireWire / IEEE 1394 connected systems.

Implementation is a piece of cake, hardware wise, on several Apple
Macs running either Linux or OSX. Stack 'em up, hook them as peer to
peer via FireWire 3-port or 6-port hubs. Best performance is from
less than 16 CPUs in a cluster, transparent bridging between multiple
clusters is accomplished with added PCI or PCI Extreme port cards.
