How big are the apps?  Assuming they only use one or two gigs of memory 
a piece, you should be able to have a 32-bit machine with lots of RAM. 
Or even an opteron with lots of RAM with a 32-bit OS on it.  That would 
save you from having to worry about any 32 vs 64 bit issues.

With that said, having a 64-bit head node and 32-bit compute nodes isn't 
difficult.  Like Reuti said, just make sure you're careful about where 
you compile your code.
