i am not much into nux, but on windows, we can inject libraries...i am 100% sure that there's easier approaches on nux, but, however, this is concept:
we need to write plugin for unrestricted ui that will read some .ini/txt/conf file.
write plugin/s for music player/s that will be loaded by that player and read it's memory for specific data: track name, play state, track id/optionaly.....
because, if this would be officially from nokia, yes, developers would have time to write plugin, but, since not all n9 users use unrestricted ui....they will not have time no matter how much we beg...you all know that...so, we need to...what? to hack
