I just came across a product called Clipstream that claims to be "Playerless Audio & Video Software". Among the claimed advantages, they list "playerless -- no downloads, no plug-ins".
If a subscriber accesses a video stream but does not download a file or display it in a client-based player, doesn't that bypass Acacia's bogus patent???
Check it out and see what you think.
