Depends what your question is!
My flat mate (he's not flat he just lives here too) follows this stuff very closely as he runs an independant record label and also happens to be an expert in cryptography and works for an ISP advising on streaming server technology.
Ask away.

Cue twilight zone music!
OK, here goes.
Imagine a streaming media file (Not Porn!!!) that is available on a secure website, as the user would have to pay to access it (Honestly, it is not Porn!!!)
How do you limit the number of times it is viewed (to prevent logins/passwords etc being hawked around to mates)
Also, if the file is downloaded, rather than viewed as a stream, is it possible to prevent the file being viewed one on the local computer without entering security details (username/password etc)
If these things can be acheived, what is involved?
Excuse the ignorance!
PS.... No... it's not PORN!
To be honest I don't care if it is porn! 
It's all ones and zeros to me.
Now, funnily enough we had this chat in the pub the other night.
As you might guess it is fraught with complication.
Stopping password sharing is impossible -
You can consider making the password expire after one or two downloads - customers however are not going to like having to apply for a password each time they want to download a file. Especially as the only secure way to issue a password is in conjunction with a credit card.
One way might be to automatically charge a credit card for each download rather than purchasing an amount of data or time - you have to be extremely careful storing peoples credit card numbers on your systems though.
But as I was pointing out in the pub it is so very easy for anyone with the know how to write software that can steal streamed data - i.e. act as a proxy server - sitting between the client and the server it intercepts the streamed data and can therefore bypass just about anything that the upper layer security systems are trying to achieve.
Alot of this depends on the cleverness of the people attempting to steal the media - you're average computer user is not going to be able to achieve this, but once the proxies are built by the 'experts' and become freeware anyone can do it.
Also software is now available to rip video and audio from the screen of the PC - this doesn't even need access to the media stream coming across the network
- a single download could release unlimited copies.
Now as far as protecting downloaded files goes
I'm not aware of any technology that is available to do this yet - I'll check with my mate when he gets back later - but again it is still open to the screen ripping technique.
If you are worried about customers distributing copyrighted material currently there is very little you can do about it apart fro mthreateningthem with legal action - which assumes you can prove they've done it.
If you are worried about losing revenue then there are simple things you can do about this. The best method is to provide a quality and reliable service that people don't mind shelling out a few $ for and accept the facy that you are going not going to realise a 100% match of cash for data out in the real world.
Hope that helps - probably not what you wanted to hear!
If you could be a bit more speciffic about you media type and customer base etc I can probably be a bit more speciffic.

Ho w about aquiring licnecs?
If you go to www.consumptionjunction.com some of their content (no not the pr0n) requires a licence before it will play in media player. Is this the stuff you were thinking about?
