Mark, I haven't been following this thread completely, so forgive me if
this
has already been discussed.
If you are boradcasting these messages all over the place, then as the
number of devices increases, you are generating shed loads of traffic
that
maybe only one or two (or even no) outputs is interested in.

Have you considered a subscription based model where each output device
subscribes to the service they are interested in (Marks unread count,
outside temp etc) and the controlling pc or whatever only sends event
data
specifically to those devices which requested it.

I know a bit more intelligence is required on the display and server
side,
but would save on potentially flooding the network with traffic -
especially
if you were monitoring something realtime....

Perhaps for greatest flexibility (to allow for dumber clients) you would
be
able to configure a "service" as either broadcast or point to
point and get
the best of both worlds.......

Just a thought.

Tony
