I am facing the same issue these days. but with the difference that my machine
will be used as a COW and not as a "real" Beowulf. Thus having the same /home
everywhere will really be convenient.

Is anyone willing to comment on the virtues/drawbacks of these solutions in a
COW environment? (or to point me to references where this comparison is made?)
