I guess that the KDE people will make a decision together with the Gnome people. And - important - they will never make their apps talk to something else than to an additional server. The server will then talk to the underlaying system, may it be direct hardware access through OSS or ALSA or through a server like JACK. So, JACK had only to deal with one application. BTW: It already possible. arts can use JACK as the soundsystem, and I have successfully used it. The question is, which audio interface should non-KDE and non-Gnome applications use? arts? esound? Talk to an OSS device? Talk to an ALSA device? Bad, because the device is most probably settled by the soundserver (JACK, arts, gstreamer, MAS, whatsoever). That's the problem. If someone wants to output or receive sound, he should write many output plugins, and because time is a lacking thing, he will only write one or two of them. Best regards ce
