I can imagine a policy mandating that for all commercial software, source code goes into escrow for automatic release 10 or 20 years later.

The company doesn't have to be around anymore, rights don't have to be negotiated, etc.

Short of that I wish more companies would do it voluntarily. I'm not into id games, but they're one example that comes to mind.

This is critical imo, if only because software are cultural artifacts that should be able to be archived just like any other cultural artifacts.
