By "modular power supplies common today" mean you models/brands and not some new sort of modular power supply technology or form factor, right? OCZ fata1ity?

I have found power supplies rather failure prone, second only to hard drives.

Googling for Ningaui cluster framework does not bring up much other than a small blurb written for USENIX in 2002. Is this not a publically available project? -- Tracy Reed http://tracyreed.org
