Forget about compiling. Just timestamp the source code, and use a digital notary to do it. Sign your code (using GPG or the like), and then email it to post@stamper.itconsult.co.uk, and make this first line in the body of your message: x-stamper-to: austin.obyrne@hotmail.com The contents of the email will be cryptographically signed by a third party attesting that the content existed at that point in time. The message you send will be hashed with whatever message preceeded yours (or its hash), (thus limiting the possibility that the third party could signficantly fabricate the timestamp). You'll get a certificate number which can be used to later locate the records if needed. IIRC, the maintainer (Matthew Richardson) has appeared in court to validate timestamps. Perhaps only British courts.. not sure on that. This service is unofficial AFAIK, but would still be difficult to dispute the evidence.
