I've just got one working that pretty much works for the VOCs in Sam & 
Max.  When it's finished, someone needs to take a look over it though.

Is it too late to put this in for the next release?  I could put the 
streaming on an #ifdef so it only runs on the DS port.

I might take a look at those as they cause me problems ;-)
