Ted: Before making accusations are that clearly wrong. Please go speak with an attorney.
I am intrigued by how you can consider Network Identity Manager a derived work of OpenAFS. It doesn't have a single line of code that references AFS in it. Nor is NIM even distributed with OpenAFS (not that being distributed with OpenAFS places it under the IPL1.0). The IPL1.0 only governs software modules[1] that are derived from software modules in OpenAFS that are licensed under the IPL1.0. It doesn't govern software modules that are original development nor does it govern software that is derived from external sources. As an example, aklog is shipped as part of OpenAFS but is not an IPL1.0 module; it is MIT licensed. The OpenAFS plug-in for NIM is shipped with OpenAFS but is licensed under the MIT license and contains components that are copyright Secure Endpoints and MIT. Unlike the Gnu Public License variants, the IPL1.0 is not viral. It does not infect other components. The license was explicitly written by IBM to permit IBM to continue selling IBM AFS and import contributions that were made to OpenAFS by third parties. Your File System Inc. adheres to the requirements of the IPL1.0 where it is applicable. It has pushed vast quantities of code changes upstream which fall under the IPL1.0 and we will continue to do so. Source code modules that are owned outright by YFSI do not need to be pushed upstream nor do they need to be distributed to customers. What amazes me most about your statements is that you are so willing to bite the hand that has fed you for the last twelve years. Assuming that you obtain the YFSI owned code developed so far, kill off any chance of YFSI investors recouping their expenses, and encourage me and the rest of the team to walk away from OpenAFS forever, who is going to support the code for you? who is going to write the rest of it? Its not like there are many options to find millions of dollars of additional investment and the technical expertise necessary to perform the work. I sure haven't be able to capture a Leprechaun and his kettle of gold nor have I discovered a cloning machine. Perhaps that is because you already have. In the end if lawsuits begin to be filed everyone is going to lose. Especially the end users that will be forced to spend vast sums to migrate their data to lesser solutions. A side note, when Peter Scott and I created the AFS Redirector for Windows we intentionally selected the BSD license to publish the work. We wanted the source code to be free to be used by others to learn from and derive new products. There are no other open source kernel file system for Windows for people to learn from other than the samples Microsoft provides in the Windows driver kits. Pete and I are both proud of the fact that the afsredir.sys file system framework driver was adopted by Maginatics for their MagFS Enterprise Cloud file system. http://maginatics.com/ Jeffrey Altman [1] The IPL1.0 does not provide a definition for a "module". However, on 1 November 2000 when OpenAFS was formed the very first this that was done was to apply the IPL1.0 on a source file by file basis. The reasoning was that the license applied on a file by file basis. Subsequent contributions of new functionality were imported into the OpenAFS source tree on that basis.
