Import proto/sign to lib/sign

[ineiti]

Re-think the usefulness of the proto-directory - is it OK to just port it back to the lib-directory? Should it be done in a way that we can import proto/sign or import proto/randhound or import proto/shamir and this way clean up the app/*-directory? This way the proto-directory could be used directly by third-party apps.

Or we just throw away the proto-directory and include it in sign

By port you mean proto ?
I agree it could be nice to do these kinds of imports. But proto/sign is very closely related to lib/conode and could maybe be merged with lib/conode instead of a new sub package.

Of course - corrected title and message.

And would you prefer throwing away the proto-directory or rather have proto/(conode|randhound|shamir|simple)?
