prelisten plugin?

[Oli Schas]

prelisten plugin would be great, because applications like mixxx are quite complicated to use in many cases
- a plugin to choose the prelisting channel (or maybe standard and prelisten out when prelistening is activated)
- a single left click in the playlist or in the bibliothek starts steaming the then highlighted song

As I am getting interested in learning python I would like to get involved in this.
Could this be so easy?

 - check if prelisten should come to work
 - call gestreamer using pygst
It would be helpful to know where and which function (?) is called by a left click in playlist or bibliothek.
is there a "hotow write a listen plugin"

I hope you like this idea, too
