I set up RUNE at my table this evening and had a blast. Have you thought about making an interactive web or mobile version? Obviously a big endeavor, but seems like the mechanics and community content aspects could translate well. (That said, it's hard to overstate the elegance and freedom of real paper.) A lightweight set of tools to just assist with the crunchy stuff would go a long way.
If you ever wanna brainstorm on something like this, hit me up! braden@legendkeeper.com
