I've been thinking about this lately, and wanted to see if anybody else thought it would be something that MC12 could benefit from. Would it be possible to implement a system, much like "recently played", which generates a rolling RSS file of the last things you've listened to. Since MC12 already had the ability to throw files up into an FTP, it shouldn't be any problem to update a server with that information. A way to let people know what you're listening to.
And yes, I know the last.fm plug-in does the same thing, more of less. But since I listen to more than 50% of my music on my portable music device, none of that goes to last.fm. This would, theoretically, allow the RSS file to be synchronized when the music device is.
Anyone think this is worth pursuing?
