Thanks for the answers. I have some new questions:
1. about the functionality - shouldn't the nowplaying only monitor one music source at a time? - should the applet display the music played by all the running music sources? - does it make sense to give the user to select one and only one music source, either from the configuration ui or from the applet directly? 2. on the technical side - regarding the addition of the MPD support, what should we consider as a data source for the nowplaying data engine: the mpd datasource (and the host/port/password) is used when a service is created or any connection to a mpd server is a data source, ie you could have more than one mpd datasource, each of them being a different mpd server eric ---------- Forwarded Message ---------- Subject: Re: questions about the NowListening applet and MPD support Date: Monday 18 May 2009 From: "Aaron J.

Woud there be any other one? there are several, such as the time, weather or twitter engines. there are two common approaches: a) put it all in the name of the source, and parse that out in the dataengine. this is how it is done in the time engine, where the name contains the timezone and whether or not to do things like the sun or moon calculations b) name the source after the service destination (in the case of mpd that might consist of the hostname and port) and then use a Service retrieved using serviceForSource from the engine to add additional information such as the credentials. this is what the microblog engine does. > Also, is anyone working in adding the support of MPD to the NowPlaying > applet? I saw in the TODO that the support of MPD is to be done. not that i know of, though people often are working on things quietly in the corners :) -- Aaron J.
