Thanks Mangus.

You pointed out some hurdles I'll have to think about (blocked files not matching the SHA and so can't be committed).

As to why I want to do this consider NSA non-export rules. Our application would be built with NSA encryption but we have foreign nationals working on the code and so they are not permitted to see that part. The makefiles look to see if the NSA encryption code file is there and link it in. If not a stub is used.
