Windows 7 Volume License

Getting ready to pull the trigger on around 700 licenses for Windows 7 Pro 64-bit. What will I need after I Ghost a machine with Windows 7 in order to activate these licences? I have read that you can actually setup a licensing/activation server?

You'll be given 2 sets of licenses. MAK And KMS... You'll add only the MAK keys into your image.

Microsoft Volume Licensing - Product Activation

You can use an internal KMS server, but it's a pain.
