How about a plugin that gives you access to your music collection when you're away from home?
The plugin provides a simple webserver and flash application for mp3 playback over the web. Examples of flash mp3 players; http://musicplayer.sourceforge.net/ and http://www.jeroenwijering.com/?item=Flash+MP3+Player
The plugin can be configured with a desired transcoding bitrate for playback of high bitrate files and also non-mp3 stuff.
Possibility to load a predifined playlist or browse/choose songs in the fb2k database albumlist-style based on for example first letter/artist/album.
Does this sound cool? Are there any applications out there that does something like this?
