Ability to copy, migrate, or export/import settings for NIS.
I have several computers on my network protected with NIS. Every year when I purchase new versions I have to go through each PC and set things the way I prefer. If I could set up one PC and then copy or export the settings to the other PCs it would reduce my work and more importantly ensure my settings are consistent throughout my network.
It's bad enough that NIS doesn't respect my settings when I upgrade. Having to reconfigure several PCs is a headache.
