What I would really like is a frontend and/or integration to Git/Mercurial that
uses Bitcoin transactions *as* the signature, which has the nice side effect of
providing timestamps backed by the full faith and credit of a billion dollar
blockchain. So what is the best way for me to stick both a git *and* a
mercurial identity hash into a bitcoin transaction?  (which leads to point 2

I'm not interested in volunteer, I'm interested in getting paid, and the
best way I believe I can accomplish that is use *my* bitcoin address in a
signature-transaction of the code I've reviewed.

What is the advantage of PGP? Far more people have ECDSA public-private 
keys than PGP keys.
