Of course I'd love to see IRIX get opened up but the community seems not willing to even try. I'd like to write a letter to the CEO though if I could get some people to support it.
From experience in pledging companies and individuals to open source their old developments, I can tell you that most of the accomplishments I made were in "solo" mode.
Opening up Irix should represent a great contribution to the remaining SGI community, and it would probably mean great PR and some headlines opportunity for their IP owners.
Go for it, dont wait for others
PS: I always found the Iris Indigo to be the sexiest computer design ever.
