Starting with the April 2004 release of the MSDN Library, they now include a cool program called NETCOPY.EXE. Its job is to walk you through creating a network setup of the MSDN Library. Once you've installed through NETCOPY.EXE, you'll do the setup for the client machines off the network setup and be able to share the whole thing. Of course, you should have software licenses for all those connecting machines as specified in the EULA.
