The FOG service can set IP Address and join your machines to your domain.

I would be using this over bat files.

I would recommend a Cisco or HP. They are both standards compliant.
I know that there are Classes / scripts out there to interface with these routers easily.

FOG is a network based solution, where clonezilla is more a media based (CD, USB, etc) solution.
That being said, Clonezilla does have network support.

Thanks for the information.
