If You're Going To Kill It, Open Source It
ptorrone writes "MAKE Magazine is proposing big companies like Cisco and Sony consider 'open sourcing' their failed or discontinued products. The list includes Sony's AIBO and QRIO robots, IBM's Deep Blue chess computer, Ricochet Wireless, Potenco's Pull-Cord Generator, Palm, Microsoft's SPOT Watch, CISCO Flip Camera and more. MAKE is also encouraging everyone to post about what products they'd like to see open sourced."

You know what ? Release the code, give a liberal licence on your own copyrighted code, mention that the floating point was Walter Bright and that he reserves all rights to it.
Then if someone wants to have a complete open source implementation, they will remove this code and replace it.
The Wise adapts himself to the world. The Fool adapts the world to himself. Therefore, all progress depends on the Fool.
I think the only way to find out would be to see if Deep Blue would make the same move again, and what the code looked like that would prompt it to do so.
IBM doesn't play chess with the Universe.
