FastPubSub Demos

No login. The host mints a short-lived access token; the master token never hits the browser. Two devices beat one.

Paint Board Draw on a laptop, watch a phone. Same public channel, 5–60 points a second, RTT on screen. Close the tab and the board is gone. Missed dots do not matter.
Online Radio One encoder, many listeners. Opus plus a snapshot of the current track, so late tuners still see the title. Some stations want a password. Dropped audio frames are fine. Live radio over pub/sub, not Icecast with a disk.
Video Meeting Room = tenant. Invite for guests, owner link for the host. Camera and mic on your channels; others subscribe with a pattern. WebCodecs in the browser, not WebRTC. This host only issues tokens and room state. Meeting media encryption is still off. Mesh demo, not a Zoom product.
