I tried PXE (both Minimyth and Fedora on the frontends), but I was never
happy with some of the NFS issues you mention.  It seemed to add lag to an
already slower system (Nvidia ION).  I then used an 8GB USB stick for a
while and while it removed the NFS issues, the USB stick was not very fast.

I recently found some Crucial m4 SSD's on sale for around $85 and bought two
of them for my frontends.  I've never seen the ION be so responsive moving
through the menus, etc.  What I thought was IR lag in the past was proven
incorrect.  The ION was slow because of the crappy OS media (PXE+NFS or
USB).  So far I've been happy with the local SSD in each frontend.
