Yes, this would definitely be desirable, if possible.

Well, the `SSIPClient' will probably always implement the API over
sockets.  Other classes, however, may implement the same API over
different communication channels.  It might be interesting to think, for
example, how DBUS might help with respect to given problems.

Just thoughts...
