Time-shift / Rewind for mp3 streams?

I noticed that it is possible to pause and resume mp3 internet streams in Mopidy. (How big’s that buffer?)

Is it possible to add buttons for –30s and –15s, so that I’ve you misheard something or just wanna hear something again, you can go back in time?

If additionally a time line, it would be important to have an indicator by how much one is going back while moving the position marker.
