BBC Iplayer - now playing info and BBC playlister

You may have heard of BBC Playlister which essentially allows you to 'tag' songs as you hear them on bbc radio and build playlists from these which you can then export to services like spotify.

I was wondering whether it would be possible to implement this in the iplayer plugin in some way. Presumably the bbc would need to allow third party access to the playlister functionality. Also I suppose part of the problem is that iplayer no longer displays song info?
