Hello,
sigul 0.94 is available at http://people.redhat.com/mitr/rpmsigner/. It contains only one minor change, updating it so that it can run against unmodified python-nss-0.4 (https://admin.fedoraproject.org/updates/python-nss-0.4-1.fc11).
A patched pygpgme is still required; it is available in the repositories at people.redhat.com/mitr .
