When a company dies (i.e. goes bankrupt) the trustee is authorised to immediately sever all licences and contracts. This means it's not possible to have any 'on bankruptcy' triggers. Even if you could have such a trigger, all licences will be void so it's no use anyway.

I think in general open source licences where a company is the copyright holder are a bit dodgy. I wonder if it's ever come up in court. (IANAL, I learned some of this stuff as my company who sells OSS had to figure out contingency for an enterprise customer)
