Have you looked at http://jkaluza.fedorapeople.org/remote-roster.html ?

Prosody and Spectrum have implementations for sections 2.3, 2.4 and
2.5, and it works fine. The Prosody implementation is
mod_remote_roster, and allows trusted hosts (currently local
components) to edit roster items for that host (mostly normal
jabber:iq:roster queries). This lets Spectrum cleanly manage the
user's transport contacts.
