So, if the scrobbling API is the same like Last.fm's, there's slight chance some client (player plugins) could support Like.fm thanks to Libre.fm (yay, Micronesian registrar must be very profitable). For example, in Quod Libet's QLScrobbler plugin you can choose to which URL to scrobble, instead of post.audioscrobbler.com you can use turtle.libre.fm or any other URL. And there's much more clients - http://bugs.foocorp.net/projects/librefm/wiki/Clients

Just give us URL to point our scrobblers to.
