I run the Indie Game Alliance (www.indiegamealliance.com), a guild of about 1100 indie publishers and designers. We already work with Tabletop Simulator and Tabletopia, and I’d be interested in partnering with Vassal as well. The way it would work is that we’d need an API we could hit to get play data for certain users (our demo volunteers) which would include what they played, when, for how long, and with how many other players.
Since this is a FOSS Java app, I’d be more than happy to add the necessary code myself; I’d just need the OK to do so. I’d love to talk to a member of the team to discuss details.
