Scrobbling to Last FM (tricky)

Many years i waiting this nice feature from Naim and now i has found a tricky but working solution. You must run Upplay UPnP audio Control Point in same network as yor streamer (i'm using my NDS) and connect it to your last.fm account (don't forget to generate md5 hash from your password and paste it). Now it scribble all music, from iPhone and iPad apps, when it streamed with foobar2000 or other control points including Upplay. Perhaps it would be interesting for community.
