im using peerJS and its configurable as described here: https://peerjs.com/docs/#peer-options-config

in my app, the peerjs-server used as the connection-broker is configurable (on the landing page). id also like to introduce configurable ice-servers.

i often notice difficulties connecting when not on the same wifi. i think introducing things like turn/stun servers would help.

which of the options makes sense:

1. a text input to specify your own turn server url

2. same as option 1 along with some default set of turn servers as a default redundency (because most users wont care about this)

3. same as option 2 with all the servers togglable.

4. ???

i understand there are a few free public ones available out there, but i dont know the privacy and security implications of using those. id like to think there is a set of trustable turn/stun servers i can use for option 2. this way, the app connection could be more stable and resiliant. but i'd need to investigate more about any set of servers i introduce into my project.
