I chatted with Ian Jackson about this, and our thought was to generate a
xen.org master key which we would keep safe in Cambridge: only he and I
would have copies of it (the two of us, for redundancy). We can also
generate a software-signing key, signed by the master key, which we actually
use for the business of signing releases from the xen-*.hg and
qemu-xen-*.git repositories.

We weren't sure it makes sense for Jeremy to sign anything since he's not
actually making releases out of his repository. If we decide that Jeremy
should sign things I think it best he makes his own key and we sign it with
the master key.
