KNX Squeezebox integration?

Jung sells it's "Facility Pilot" KNX visualisation software (see here) that has a module, called "XPL editor", to control Logitech's Squeezebox system ( or Slimserver or Squeezecenter... it's all he same). We can read on the Falicity Pilot catalog (pdf link here):

XPL editor for audio applications There is an increasing desire to combine home and building automation with streaming of digital music. For instance lighting and music control can be integrated in scenes, which can be selected at the push of a button from anywhere in the building. One of the best systems for audio streaming over IP networks is the Squeezebox-system from the company Slim Devices, Inc. (Fig. J). Audio streams are transmitted over Ethernet or wireless (IEEE 802.11) networks from a server with the open-source SlimServer software to Squeezebox music players, and in turn controlled by the Facility Pilot XPL editor. Supported audio streams are for instance Internet Radio, MP3, WAV, WMA and Ogg Vorbis. We strongly recommend not to install the SlimServer software at the PC running the Facility Pilot system, since the SlimServer could impair the proper operation of the automation system. The XPL editor of the Facility Pilot system controls the SlimServer and in turn the Squeezebox music players via the XPL data protocol, which is standardised by the XPL project. Among other possibilities, using the XPL editor, push buttons and dimming functions can be used to control volume, playlists etc., or messages can be displayed at the music player's display. For the indication of tracks or playlists KNX front end devices as FD RCD, colour touch panel, etc. can be used.

Bare in mind the price of the software. It may not be for affordable to all purses :-)

EB - Update 2010-03-22:

It seems that it is ESF Software GmbH who makes this Facility Pilot software for Jung but they sell it under the name of Agentilo You can find more details on this software on http://home.agentilo.com/agentilo-overview and specificaly on how to use the XPL Editor in http://files.agentilo.com/docs/en/v2.1/EsfXplEditor.pdf.

I tried to edit my previous answer but I keep getting a Http Server error 500.

Nevertheless, I just wanted to add infomation on another product that allows you to control the Squeezebox/Slimserver from KNX buttons. This one is the EIB Port from b.a.b technologie GmbH (see http://www.bab-tec.de/index.php?id=466&L=1 ) . You can read the setup manual on http://www.bab-tec.de/fileadmin/Dateien/Dokumente/Bedienungsanleitungen_eP/Instructionsheet_EN_eP090_20100318.pdf. There we can read

11.3. Music control with Squeezebox / Multi- Room- Audio equipment

eibPort joins mulit-room audio equipment with world of KNX/EIB. SqueezeCenter as server and Squeezebox -units as streaming clients will be integrated therefor to local network.

SqueezeCenter will be controlled out of KNX/EIB world and revers, informations will be sent from SqueezeCenter to world of KNX/EIB! Push and display elements, they will also substitute “classical” multi music control can also be combined with light scenes.

These functions will be made possible through xPL protocol (extreme simple protocol).This protocol, that you will find in SqueezeCenter and in equipment into building control.

eibPort therefor offers job SB-control, xPL receiver. Telegrams out of bus will be transformed to corresponding xPL instructions or reverse transformed to show information software, which will again control Squeezebox units. (...)

If you happen to use a Gira HomeServer you also have the possibility to use an add-on that will allow you to control the Squeezebox. This one is called HSSlim by Dacom. See http://www.dacom-homeautomation.de/labs/index.php?option=com_content&task=view&id=79&Itemid=83 (German language link)
