pwscf has been used successfully on openmosix clusters.
there are some pitfalls, though.

- you have to be careful with shared libraries when
  compiling the binaries or else the processes won't migrate.

- you need to use a networked file system to store the
  scratch files. this can put a severe load on the network.
  even NFS over gigabit will only survive small to medium
  size examples.

- parallel jobs are particularly tricky. using LAM/MPI in
  TCP/IP-only mode is supposed to work in general, but 
  i am not sure if anybody tested it with espresso yet.
