If you take a look at some of my previous posts about Two Hour Dungeon Crawl and 5150, you can see how I've been using TS as a digital gaming table.

I don't necessarily need a table with a grid drawn on it as long as I can specify a grid or no grid, or have the ability to overlay my own layers on top of the table. Sometimes you need hexes, sometimes squares, and sometimes you just don't want any distraction at all. Especially if you're working with 3D terrain.

I am all about using Scheme, as an old school Common Lisp and Scheme programmer, but you might get more traction with the mainstream user if you go with Python or Lua.

(If you want extra points with me, you'll support an Erlang node which can be taught to from any machine on the network – but I'm a weirdo and my suggestions should not be taken seriously.)

Some kind of system which would support my tabletop gaming both wargaming and really ridiculously-indie role-playing games would be great. I've been struggling and making do with TS for quite a while because there's really just nothing out there to compete with it.
