That didn't really answer my question. If there's someone signed up and motivated to do the hard work of getting these changes integrated into the upstream applications then that makes us more interested. If, however it was some weekend proof-of-concept hack which shortly dies an instadeath then... meh, not so much. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
