Embeding Justin.tv password protected video into a site

I need the ability to embed a password protected [login to view URL] video stream into my site, without the need for anyone on my site to enter the password (gets sent automatically somehow) and it also has to have the best possible source masking in place - i don't want nobody to be able to identify or make it VERY difficult to identify the direct source from [login to view URL] For any more questions just e-mail me!
