I agree re. the single system image. Our clusters work that way, and you 
have the choice of running in a ramdisk mode
as you have done, or using the local disk for tmp/swap, or a 
conventional hard drive install.

Fedora isn't the only kid on the block, and given the short support 
lifetime I would recommend against using it in a cluster.
Fedora is clearly aimed and billed as a cutting edge distro, which will 
have a release every six months.
Most of our clusters have SuSE linux installed, which runs very well on 
Opteron/EMT64.
Our commercial customers tend to go for Redhat Enterprise or SuSE SLES, 
for compatibility and support of ISV codes.
