+1 to mobile vassal!
That would be nice. They'll need to rework the UI a bit though. I tried some VASSAL on a touch screen monitor a few years back that I laid it flat on the table to get that board game vibe. Some of the menus wouldn't work well and getting right-click options on unit counters to work was hit or miss.
Also, if the mod has a lot of windows crowded on the screen it can be a real pain to try and access each one with touch. I still needed a mouse to get various things done.
