Hello,
We're in search for a WMS (Windows Media Services) authorization plugin.
This should include if possible some sort of referrer protection, and authorization based on hashes, tokens, user/pass whatever.
If such plugin with any options is available to buy, or if we could hire someone to do this, or someone with contacts, we'd appreciate it! 
Been searching for ages now, without much luck 
 
Thanks in advance!
Wesley
ps: We run Windows 2003 Enterprise edition.
