Maybe a solution is to find some unpaid interns or volunteers, NDA them, and unleash them on the technical challenges (and scrubbing the obscenities from the comments). That leaves only the legal question for the company.

It could be a huge PR boost. EA games got some good mileage out of releasing their older titles like Tiberian Sun as freeware. Imagine if they unleashed them as open source, and thus made them into a learning tool (like a textbook) for future generations.
