Do you know what those standards are? IDo you have any specifically what
configurations are not set up correctly?

It would seem that this activity must implement the DBUS methods outlines
here:
http://wiki.sugarlabs.org/go/Development_Team/Low-level_Activity_API#D-Bus_Methods.
Based on what these methods are, I think its likely they would have to be
implemented from inside Empathy itself since they change, what I assume, is
internal Empathy state.Especially the Invite() method.

Sugar already has a

Having Empathy handle this as the back end would be cool, but I can't see
how this would be doable without at least some additions to the empathy
code base. Even if its just to set up a few simple DBus method calls,
change a few environment variables, and parse a couple of Sugar specific
command line arguments.

Best Regards,
Alex
