Thinking about it, one easy way to design this would be to assume the available
clients will change infrequently, and use this sort of pattern:

interface o.fd.T.ChannelDispatcher.Interface.PossibleHandlers

    method GetPossibleHandlers(a{sv}) -> as

        [... documented as before ...]

        Clients MAY cache the result of this method (or more practically,
        decisions based on the result of this method), and use HandlersChanged
        to detect when to update their caches.

        | For instance, the Empathy contact list has a "Share my desktop"
        | menu item, which is visible when a VNC tube handler such as Vino
        | is available.

    signal HandlersChanged()
        Emitted when the set of available handlers has changed. Clients
        that cache the results of GetPossibleHandlers SHOULD call that
        method again.
