I don't actually know if this would apply to the BYOND Pager or Dream Daemon, but it would be nice to be able to programmatically specify some keys/passwords to log in for testing, automatically.

My intended workflow is something like this:

byond.exe -key=DivineTraveller -password=MyAwesomePassword -fake -dmb=localhost:12276

or

dreamdaemon.exe -keyval=passwords.txt

where passwords.txt looks like this:
divinetraveller=MyAwesomePassword
t3hc4ctu4r=MyOtherPassword
irt3hli3kpi3=AnotherPassword

Alternatively, support for x guests would be cool too - I don't really care if I use keys or guests, but one or the other would be nice.

Why? I don't want to log in four keys to test something, and I can automate this with my sublime text plugin. Any support for this, regardless of how primitive, would be fantastic. And hey, if I can already do this, that's even better. I don't know what arguments byond.exe, so it might already be possible for all I know.

To clarify, I do not want a headless DreamSeeker - just a way to log in programmatically.
