I know anything can be forced to work over a WAN, but is GFS a good 
choice for this purpose?

I've been looking at OpenAFS for this, but the failover for the one 
writer in the  "one read-write/many read-only" model doesn't look very 
strong as well as the "always grant" locking and lack of inter-directory 
hard links and generally non-posix semantics doesn't make it look like 
the best choice either. :-/

Is GFS only for SAN style shared-storage clusters?
