Network Home Folders w/ AD for Lab

Hello all, Have a golden triangle here and are looking to set up a lab full of Mac with network homes. We are using AD to authenticate, but can't alter the AD profile, as we are but a small school in a large University. Also, it would be unwieldy to create the homes ahead of time for the ~1700 student that could be using the lab. Is there a good way to configure the machines (ideally through WGM, though a login script would work as well) to use AD for authentication, then automatically create a Home Directory directly on an AFP share. Any help or ideas would be appreciated. Thanks.
