How to protect MMS or HTTP or RTSP stream from leeching?

hey all

I am new to windos media server.

I saw so many web sites Running their Livestreams (Paid) or Free.

All in Most can be seen from web source(html) and can be use on any other site.

like mms://domainname/pp

I want to make a new server for streaming. But want to protect my stream that can be play only Internal to my own Website Mediaplayer(Windows Media player only).

So any users can see the MMS:// (Address) from(Html) source or from any source. He can not play my stream to OWN Windows Media Player or Embed them to any other site.

What Should I Do for this?

Pm me I can give you the Example who did it and You can not play or put that mms on your own server or WMP.

Thanks in advace becasue I am Totally new to WMS 2003 .
