As far as Birdie is concerned: I don't have a contact to its author. Do you? Does anyone in the community have?  

I am pretty confident you will find him at https://www.linkedin.com/in/trondwernerhansen

For the record:

If anyone is interested in setting up a bounty for AOS sources then I'm willing to put down $1000. Personal, hobby, non-commercial money.
Make it for 3.1 only if that makes it any easier.

(The bounty should have some legal-speak that indemnify the buyer(s) if the rights are disputed at a later date.)

how are you going to make sure you are buying from the actual owner and that there will not be any claims from third parties in the future?

That is of course the tricky part. The seller should take some legal/contractual responsibility to accept ownership over future disputes.
Which is basically what they have done anyway by selling 3.5/3.9. An attempted buy-out should say something about their confidence in the legal side.

OTOH, internet exposure of source code can turn the reaction knob to 11 and flush out someone who has been biting their tongue or just been sitting idle (or simply been unknowing) since C= died.
