You might want to implement this on top of People [1]. It makes sense
as People discovers information about a contact's avatars from
different sources (telepathy, gravatar, and potentially all the
services providing avatars), information which is exposed on D-Bus.
Needed bits to add would be the access (the service will provide you
with URIs, base64 encoded data, or whatever representing the avatar)
and caching of the data in a library accessing the People service and
providing an API to be directly used in applications (no need to
expose that one on D-Bus).
