This sounds good. I wonder how we would integrate this into =E2=80=9Cguix pull=E2=80=9D. For authentication to work at all the user would have to have *all* past keys. (I=E2=80=99m missing at least one of the keys, because only current = keys are contained in the keyring on Savannah.) > I have plans to make things faster (independently of the cache) by doing > OpenPGP signature verification entirely in Scheme instead of spawning > =E2=80=98gpgv=E2=80=99 every time.
