Hi,
I would consider learning C etc myself to try and get this functionality
(I
learned Java as part of my degree) up and running, but sadly I probably don't have the skills to contribute.
AA under linux is not app-dependant afaik. It's driver dependant, so you'll have to setup your graphics card driver to turn on AA for OpenGL based progs, prior to running the game under WINE.
OpenGL offers AA itself using the multisample extension. The level of AA is a property of the pixelformat in use for opengl. Due to various reason the number of pixelformats is limited and for that reason games running on Wine don't show AA. This is the case for both OpenGL and Direct3D.
