But maybe gamin can query local FAM daemon (or only delegate calls via
libfam).

But it is a regression for NFS users: Either users have to recompile
their gnome-vfs or distribution package maintainers have to continue in
using dirty tricks (two versions of package, wrappers for dynamic
decision on using of FAM or gamin, replacing gamin by fam after
activation of NFS etc.).

Integrated FAM support without disabling inotify would be nice. Either
as two backends or FAM as fallback if inotify fails.
