note that autocad in its current version will need license file an dwill search the network if someone is using same license more then once at time etc, so difficult unless you have full agreement with autocad to be allowed to have thinapped version in your network. (which exists)
But such biult will anyway not work from a flash stick probably, so why to bother.
