I have been playing around with python and django the last coupon of weeks and I have created a NFS Manager module. You can grab the source code from: http://github.com/bmaynard/NFSManager
It is fairly basic at the moment and I havn’t implement all the options available for NFS but you can manage several servers from one place 
. To use the module, you create new servers, then setup the shared directories and clients. After you have set everything up you can go to the server list and push the changes across from the action drop down.
If you have any comments or suggestions then please leave a comment, I would like to try and make the module more powerful.
