Erik from IBM wrote to us to confirm that IBM will be a "open sourcing" AFS. What's actually going is that they are forking the code, as not all of the code can be opened for "technical or licensing reason". So, there will be IBM AFS, which they will support, and Open AFS which will be the open code. The license is going to the be the IBM Public License which is an OSI approved license. Overall good news for a very scalable, secure file system.
