Working with keys with passphrases works when using an archive-directory
(which must be kept!)
See:
http://lists.gnu.org/archive/html/duplicity-talk/2008-05/msg00067.html
http://lists.gnu.org/archive/html/duplicity-talk/2008-05/msg00068.html
(in this thread I used two different keys for --encrypt-key and
--sign-key, both with passphrases (on their secret-keys of course))
Using this it's possible to create backups against a gpg-key, whose
secret part is nowhere on the system to be backuped. Furthermore one has
control over who can use these backups by using several --encrypt-key
options.
(To let gpg use this key, one has however set the trust on it. Either by
using gpg-options to trust it explicit (I don't remember which, I think
something like trust-model or the like), or by setting the trust-level
to ultimate with "gpg --edit-key")
