A few questions regarding audio streaming

[mahender]

1. I login as admin and start to play a playlist. How can other people on the internet listen to the same songs (and the same position in the playlist as I have), viz. listen to the same player/position?
[update: that is perhaps doable using the <host:port>/stream?player=<playerID> instead of using <host:port>/stream?playlist=<playlilstID>]

2. Once I start a player, I can use xmms/winamp to directly listen to http://localhost:8080/stream?player=1, but if I try the same using rhythmbox or vlc, I get html code!!
[update: using xmms/winamp does not require me to login, using rhythmbox/vlc perhaps does, I do not know why; using an existing player shouldn't have required authentication, unless the stream access URL has been configured with authentication requirements as well (which is not the case I think with this software)]

In a nutshell, I want to provide the people on the internet the ability to tune into what I am playing; http basic authentication is supported for this by winamp/vlc, but the authentication for a stream is different from authentication to access the web-interface of subsonic.

3. From above, how can I configure basic authentication for the stream URL?

4. If I start a player using login from localhost:8080, can I then access the same player over my public URL, like myhost.mydomain.on.internet:8080/stream?player=1 or myhost.mydomain.on.internet:8080/play.m3u - is there a URL without requiring login to download the playlists configured by a user and to see which of these is playing at a given time?
