As well as the option to enter a room code, you could type in an address to connect to a community hosted server. Community servers would allow somebody to have much more control over parts of the room such as video sources and bitrate. This would also take strain off of the bigscreen servers and allow for communities to run with much higher bitrates.
This would obviously be a security risk as the server would see information of the clients. Because of this, this could be a more closed feature with you having to enable it in settings with a disclaimer and stuff and also have something like an EULA for server hosts.
I just see this as a good feature especially with some communities have started building proper systems yet being limited by the built in hosting solutions. An example of this is how bad 3d looks due to the resolution being so low. A server could increase their resolution to higher amounts.
