Usage and Notes

Viewer side effect that's sent from one viewer, and broadcast to other agents nearby (selection beams, PointAt, LookAt).

viewer-->sim (single effect created by viewer)

sim-->viewer (multiple effects that can be seen by viewer)

The AgentData block is used for authentication for viewer-->sim messages
