The nuclear security people were interested, but ultimately passed due to the size off the player, and the need for very long term access to the technology.

DEC had an optical WORM drive, I think it had rather large media.  Not sure if that's the one you're thinking about.  I believe it shipped but it doesn't feel like a particularly successful product.  (Then again, the worst I remember was a networking device that sold a total of 3 units over its lifetime -- the DESNC...)
