Thanks! I haven't actually seen their setup live yet.
There is a bunch of command line options for starting the game (listed in readme.txt file), but no option to directly select the match type. Now that you mentioned it, I wonder how they deal with this at the museum and why they never asked for such option. I will add it in next version.
You can edit ~./astronautics/configuration.xml file manually for some extra options like disabling keyboard/mouse controls if you plan to play on phones only.
Maybe you could post a picture/video of your setup here, when it's done?
Anyways, let me know if you find anything else that would help with setups like yours.
