 Hm. I just skimmed over the patch. I will look more into it soon.

 I wonder if we can move all this file-creation/reading logic to
 `__init__()` instead of `get_public_server_options()`. It would be more
 suiting I think.

 Also where is `SERVER_PASSWORD_FILE` initialized in the pushed code?

 We should also think what we want to happen if a person sets up a
 `ServerTransportOptions` line after a `SERVER_PASSWORD_FILE` has been
 created.

 Maybe we could have a more descriptive log message than `No password found
 in transport options.`. Maybe it should be directed to the bridge operator
 and say `No password was specified. Generating and caching a new one.`.
 Maybe there should also be a log message for `Found a cached password.
 Using this one`.

 We should also figure out what happens if `writeToFile` fails. This might
 be better handled by moving this logic to `__init__()` I think.
