There is nothing to stop you from having NFS exports run on all of the 
nodes simultaneously. Divide up your clients into groups so that each 
group mounts a different NFS server, and have the floating IP of the NFS 
servers as a fail-over resource.

There are, however, a lot of potential performance issues you will 
likely encounter in such a setup (attribute caching on NFS, lock caching 
on GFS, etc.).
