Maybe we can save up and buy it from this dude, then open it something like what happened with Blender? I hate the idea of hobbyist licenses - it reminds me of the torturous OpenVMS hobbyist program or whatever the hell that incomprehensible situation is.
Also, curious how old is the IP owner in this situation? What happens if he croaks with it?
As with any asset, it would become part of his estate, to be sold to pay its debts and/or divided among his heirs or left in his will. It may result in another opportunity for someone to acquire it at probate.
DKS doesn't own the IP, and wouldn't sell (to me at least) any unpublished sources, schematics, etc. for any price at all.
As of several years ago, though, he was willing to part with a number of new-old-stock Ivory CPUs, for roughly the cost of their weight in gold. (And periodically offers Ivory machines for sale on eBay. Here's what these look like: http://www.loper-os.org/?p=2857 )
"Wish List: a knowledge-based operating system running on a MIMD parallel machine. The system should exceed the productivity of the Lisp Machine by several orders of magnitude and integrate seamlessly with a global knowledge base and with a global computational environment."
AFAIK it's still owned by one John Mallery, a wealthy MIT prof with military and intelligence establishment connections.
My favourite "conspiratorial" hypothesis concerning this question is that the Symbolics IP was ordered to be perma-buried for "national security" reasons (as it threatens to make practical systems with capabilities much superior to today's state of the art, but running on early 1990s IC fab processes) and that Mallery (who, per rumour, purchased the IP for next to nothing via a backroom deal) was the designated undertaker.
AFAIK it is still unknown whether the chip die masks, source for (the parts not included on the tapes/CD) os/compiler/IC workflow -- was even preserved to this day.
It probably can't be understated though how important it was that Ton, the original author was spearheading that whole thing. He would have had both an existing relationship with the investors, and enough clout with the community backers to envision a future for it... trust which was obviously well placed.

keep this in mind when you pick a software license.
