Thanks for sharing!
I have a FMOD dll in the works and it is suprising, that the GS media system doesnt allow seamless streams. I am even able to stream 40mb waves without any lag and especially streams from any internet source are most times faster that streaming the same file from HD with the GS media_ commands (requires a broadband connection

).
Did you managed to transform the A6 coordinate system over to OpenAL so that its 3D sound device is working correctly. I have some trouble with this issue on fmod, but the rest works fine for me.
Cheers
