The first scope of this project is to make a portable software which can emulate every function of this engine. GemRB will work on Unix/Linux Systems, MacOs X, and Windows.
To play a game using GemRB you have to own a legal copy of it, since we do not distribute any part of the BioWare work.

Don't hold your breath, it is still under development
