glusterfs and nfs mix nicely - you can use the native glusterfs client 
(I do), or you can use an nfs client to access the glusterfs server.

You can export a folder using both an nfs server and a glusterfs server 
at the same time, which is nice for a gradual migration.

I use glusterfs over openvpn + cable modem, and it seems much more 
responsive than nfs ever was (judged using "ls -l"). But I haven't 
benchmarked it objectively.

I'm not sure about that...

Anyway... it sure solved a lot of stability problems for me. glusterfs 
deserves to be better known as a reasonable NFS alternative.
