Ian Lance Taylor visited SCO to find out about their case against IBM and linux. There was no direct access to legal documents and SCO are still keeping the detailed evidence and claims under wraps but there is more detail here than in previous media reports. Taylor did have to sign a draconian non disclosure agreement but was shown a piece of code that SCO claimed infringed their rights. Taylor wasn't convinced by the example and wasn't able to provide a copy because of the NDA but his perspective was that that it was possible that some code may have been copied from unix into linux but that there were numerous examples of the same code to be found easily around the net and that SCO were stretching the definition of what constituted a derivative work. Nice to see a few scraps emerging on this saga but the explicit evidence and court documents remain elusive and beyond the scope of open scrutiny for the moment.
