Hi Brad,
   Cool that you got it working.

   One thing I've run into with NFS mounts is that rebooting with one
mounted can cause problems and long delays. Rick Stevens pointed me
toward an option called '_netdev' in man mount. (I think)  Using this
option tells the system that networking must be up before this is
mounted and that this must be unmounted before networking goes down.
Good option. Here's a few NFS oriented entries from my machine's fstab
file for you to peruse:

dragonfly:/Musiclib     /mnt/Musiclib           nfs    
noauto,user,rw,_netdev,proto=udp        0 0
dragonfly:/home/mark/MusicLib /home/mark/RemoteMusicLib/ nfs   
noauto,user,rw,_netdev  0 0
myth14:/video           /video                  nfs    
auto,user,rw,_netdev,tcp,rsize=8192     0 0

Note the inconsistencies! 'proto=udp' vs. 'tcp'. Who knows?! ;-) I
should probably clean that up.

Cheers,
Mark
