When SCO launched it’s now infamous lawsuit against IBM on March 7, they gave IBM 100 days to resolve the matter. That 100 day mark puts the deadline at June 13. SCO has said that it has the right to cancel IBM’s rights to Unix System V if a deal isn’t reached.
SCO has allowed a handful of analysts to see the offending code, but they are all bound by a Non-Disclosure Agreement (NDA). Of course, releasing blocks of code to the public without an NDA would be the same as what they claim IBM has already done.
With the 100 day deadline approaching, SCO will probably take some action in the coming days to show it wasn’t bluffing, but revoking IBM’s AIX licence might be going a bit far. Time will tell.
