Btw, do you have a brief outline on how you are going to do the
extension to signature verification? Nothing formal, just enough of an
outline that I can see where in the flow it will be plugged in.

I was wondering how the whole signature signing and verification will
be done, i.e., where do I get the signature, how and who will verify it
(I'm guessing the purgatory code), etc, etc.

Thanks.
