I would send them the source code on a DVD with one part of a 3-part key. You make a literal verbatim copy of the DVD. You now have one part of the three part key on that DVD, which you send to them and keep one for yourself. Make two more DVDs, each with one of the other two parts of the three-part key. You then hold all three parts. Any two of them can be used to decode the original encryption. You can use yours and the copy you sent to them, or both of your copies, or their copy and the other one, etc. This will verify that what you sent them is everything, and what they would present in court is a true copy of what you actually sent to them.

Using this, you can go back into the source code and verify that the condition of failure they're ascribing to you and your work DID NOT exist in the source code you released to them -- assuming it actually didn't.

Still though, the best thing is to get the template letter to release all liability.

UPDATE: To be clear, three files on each DVD:
(1) unencrypted.iso, they can copy this to their hard drive and burn the source code DVD from it.
(2) encrypted.iso, a literal copy (encrypted) of "unencrypted.iso" that when it is decrypted will be an exact match.
(3) part1of3.key, the part1 encryption key part.
