I strongly support your request about NFS support.

I have to run a script manually after boot. Have not got it to start at boot yet.

My script:

/etc/init.d/rpcbind start
/etc/init.d/nfs-common start
mount -t nfs 192.168.1.107:/mnt/raid/music /var/lib/mpd/music/Server
/etc/init.d/mpd restart

This works fine on my system once up and running.

I would say, make some code for it so they only need to add a few buttons and a webpage

So if the correct command is:

sudo mount -o nolock 192.168.1.104:/export/Media/Music /mnt/NAS/<MOUNT_POINT/

The IP:location should be editable as well as the mount_point so youll get to see the correct name in the database, so you would get a command a little something like this:

sudo mount -o nolock %ip:%location /mnt/NAS/%mount_point

Put it in a python (or what style/language is prefered) make %ip %location %mount_point variable
Then the scipt can be incerted in the other startup scipts that already run.
And the variable filling, shoudnt be to hard for the webpage creators and submit it to them so they can test and implement it.

For the people who dont know how to start a script when there system starts, you can do it with bash.bashrc or as a cronjob.
For a Cronjob do:
crontab -e
Goto the end of the file add:
@reboot /[complete path of the script]

[edit] mabey you want to give the R-pi a few seconds to get the network online then youll need to put a delay in the scipt.
