Microsoft Releases CIFS Docs -- Free Ball & Chain

juan large moose writes: "Microsoft has released documentation on the CIFS protocol suite, but there may be a catch. The license says that the documentation is available for review, but no one may implement the described technology without signing a 'royalty-free' license agreement. Some reviewers are reporting that the document provides less information than the earlier IETF DRAFT CIFS specification, and may in fact be a cleaned-up version of an outdated Storage Network Industry Association CIFS Document. These other documents do not have the restrictive license."
