Was able to test it a little.
It runs (after a long startuptime) and is running pretty good. I imported my Musiccollection without much hassle.
Unfortunately it doesn't run very stable.
When you play a song (takes some time after clicking it) and select the preferences for example it crashes.
Also when you select the Miro Playlists it crashes.
I deactivated some of the plugins to make it more stable.
The Audioplayback (with and without equalizer) seems to be pretty solid and not very resourcehungry.
It didn't even skip when I opened chronium in the background, as audacious does.
The built in volumecontrol works but you can't use the progressbar to skip to a specific time in a song.
Also I had a lot of random crashes during testing.
In some of them I was just thrown back to the desktop, but sometimes it hangs completely and I had to hardreset the Pandora.
Unfortunately my girlfriend had her Ipod Touch with her, so I couldn't test the connectivity of iDevices.
Will try this later.
All in all it runs pretty decent but it crashes too often for being useful.
Some screens:
Main window in fullscreen mode.
Minimode.
Fullscreen currently playing.
As you can see, it fits the pandorascreen really well.
Without the crashes and some improved performance it would be my favorite audioapp on pandora!
