I think both these could be done by a pubsub device (separate process
or embedded) that uses XPUB to detect new subscriptions, and
heartbeats to signal publisher activity (and turns these into EOS).

Perhaps a useful example for the Guide. If you need this urgently,
contact me off list and I'll put you in touch with someone who can
build it for you in exchange for cookies.
