I agree but the processors are already past the 1.7 g4.  I was merely 
saying that for what we are doing it is fast enough.

I had thought of mentioning that, but there's almost no commercial 
support for Linux on PPC by independent software vendors.  It seems a 
little pointless to me - if you're going to run Linux, you might as 
well run it on the best supported platform, which is still x86.

True but I was putting this out as a proof in principle that Linux can 
run on PPC

I'd like to hear more, because I don't believe it.  Can you power cycle 
a crashed node remotely?  What sort of remote console do you have?  Can 
you do everything you need to through a command line as well as a GUI?  
I know GUIs are friendly, but when your cluster gets large you get 
tired of clicking buttons *really* quickly.  Your requirements are 
probably different from mine, though.

You can admin remotely the tools are included with panther or jaguar.  
As far as I know the remote capability is the same as if you are 
physically present but I cannot say for sure.  Yes you can use command 
line for everything. you are right that some of this depends on scale.  
you should also take a look at "big mac" at Virginia tech.  A cluster 
of 1200 g5's that is the 3rd fastest supercomputer in the world.
