While there is IP over 1394, and Oracle has released their clustering 
librares over 1394 as open source, it seems that the "400 MBps" and 
"isochronous" invite to mistake 1394 as low-latency. Alas, it's not. I've 
posted some real numbers to Beowulf some month ago (which were quite 
appalling), and Becker meant they were optimistic. 

But, it is probably still worthwhile to use 1394 for some applications 
(like Oracle's clustered filesystems, maybe with built-in databases), 
along with onboard Ethernet. Do they have to share the PCI bandwidth 
internally?
