Theoretically, yes.  However, I've never done it so I don't know how
hard it is or exactly what problems you'll run into.

This is the main problem, getting the daemons and the files they require
onto the nodes, but even that can be tricky.

This is probablly your best bet, but I'm not sure how it would slow down
local HD access.  With PVFS you take a number of slave nodes and speicfy
them to serve data, and a filesystem is created that is split among all
those nodes, much like RAID striping.  If anything, accessing a file off
a PVFS filesystem should be faster than off an NFS filesystem due to the
distributed nature of it.
