Thanks for posting the recording! Enjoyed watching it. Just two small notes:
- In your slides you could use widget_styles (http://docs.missionpinball.org/en/latest/examples/widget_styles/index.html) so you don't have to repeat the font name and size all over the config
- There is a working prototype for connecting VPX and MPF (https://groups.google.com/forum/#!topic/mpf-users/bS7vtUaWVf0). We will probably publish some updates it in a few days with better tutorial and examples.
