Interesting use case. If we aren't going to store directed presence
(which a bunch of people oppose for resource issues), I would say that
instead of the last broadcast presence (in all cases) we could create a
protocol extension for probes in general. Some sort of protocol when you
just want to know the last presence you received is still valid.
