Description

We shouldn't assume that every room will use full mesh. Ideally rooms should be have configuration along with the policy server explaining how to distribute events amongst the participating servers.

We could have a list of distribution protocols in the room config with two transports that servers MUST support:

1) The current full mesh transport.
2) A simple list of endpoints to pass events to.

Rooms SHOULD support at least one of these two transports. A server can then always join the room by falling back to the simple list of endpoints if it doesn't understand the other federation protocols in the room.

Research direction

No file or test is named. Start by locating the current full-mesh transport and the room and policy-server configuration in the Matrix specification, then determine how this proposal fits those definitions. Done means the specification clearly defines the supported transport choices, fallback behavior, and room requirements.
