[Web4lib] Streaming media

Just to follow up on this thought...
One of the consequences of the fact that Flash video tends to be progressive load instead of true streaming is that it is more difficult to prevent users from making a local copy of the content.
In most streaming media, the user only has access to the stream, not the actual file, and so they must connect to your server in order to view the stream.
With progressive download flash files, the flash file itself is downloaded, and an enterprising user can view the source to get the URL for the flash file.  I do not know how you might protect against this if you need to restrict access to the source media.

Technically they don't stream unless you have a special streaming server 
(using "Flash Communication Server software").  For many sites, what you 
have instead is "progessive download".

That said, you see this kind of video all over the place nowadays -- 
everywhere from NYTimes.com to YouTube.com.  Where it's particularly 
handy, assuming "progressive download", is in shorter pieces (<10min) or 
where you can take advantage of Flash interactivity.
