Request: Vassal Portable

Linkage: http://www.vassalengine.org/

Vassal is an open-source board game engine that allows you to play board & card games online & via e-mail. It has a crapload of modules (games) that you can pick up & play with others.

It seems like something that would be cool to have in the Portable Apps library, especially for gamers on the go.

It seems to run on Java (which might be an issue), but how hard would it to make this portable?
