So you want to build uni-directional web-of-trusts for each key usage ?

this gpg anchor and all keys it signs, can be used for release signing
this other gpg anchor (and all ...) can be used for pkg-bin signing
this thirds gpg anchor (and all ...) can be used for third purpose...

All those anchor needs to be signed by the developers directly.

I'm not talking about signs on the anchor, I'm talking about the signs that
tha anchor is allowed (by policy) to make.

Also, how do I limit the pgp trusts in time ?

I will trust my CA ~ forever, how can the CA limit what rights its going to

X509 sucks, but I think PGP doesn't even try to solve any of more then just
establish identities, it never communicates what the signer intented
he/she/it would allow the signed certificate to do.
