Would it be possible to instead of using the flash player for audio playback, use HTML5?
This should be added at least as an option, as it would also open up a lot more customization for streaming options (eg. opus, ogg). I know there are third party html5 players, but it's obnoxious to install software when I'm on various different machines throughout the day, and sometimes not even an option (eg. at the library).
I think this should be pretty easy to implement, if I knew where the files were I might try setting it up myself, but I know nothing of java.
