Why not just use openssl instead of gpg then? You have a root cert which sings the individual pub keys of every dev. To verify the packages users just have to trust the root cert. This does even support some kind of revoke etc.. (you could even sign the root cert by an external entity like cacert to make it even more secure. -- Pierre Schmitz, https://users.archlinux.de/~pierre
