Ok folks, here is the new proposal:
input.lastfm(user:"...", password:"..", ~url:"lastfm://...")

The protocol handling is even more easy, it is only a webservice!
See: 
http://mattdbrown.blogspot.com/2007/07/internets-using-lastfm-to-obtain-xml.html

* get sessionID: URI: handshake.php?username=[USERNAME]&passwordmd5=[mp5]
* set station: adjust.php?session=[SESSIONID]&url=[LASTFMURI]
* obtain XSPF playlist: xspf.php?sk=[SESSIONID]&discovery=0&desktop=1.3.1.1

Then you got a playlist that form:
<playlist version="1" 
xmlns:lastfm="http://www.audioscrobbler.net/dtd/xspf-lastfm";>
<title>+rocksteady+Tag+Radio</title>
<creator>Last.fm</creator>
<link rel="http://www.last.fm/skipsLeft";>20</link>
<trackList>
    <track>
       <location>http://************************.mp3</location>
        <title>Night and Day</title>

        <link rel="http://www.last.fm/freeTrackURL";></link>
    </track>
</trackList>
</playlist>

You then need to download each track *one by one* and queue them..

The url can be avoided at first, and set later on, so we could export:
get_url
set_url
As long as possibly:
(un)love_song
(un)ban_song

Also, the source may behave exactly the same as a playlist, allowing stop 
start, 
but should be refreshed regulary, so I guess this input could use playlist..

I'll look at the implementation but I'd still love some hand from the gurus of 
course :)
