[Opensim-dev] Proposal: notify clients when Robust changes a user's inventory

[Mister Blue]

The modern code pattern for this sort of thing is for there to be an
underlying notification service (like MQTT, AWS/SNS, ...) and to build IM
and server-to-server comms on top of that. A serious refactoring would be
to rip out the existing push directed IM system and replace it with a
pub/sub notification system that inventory change notifications, HGIMs, etc
can be built on.
