As far as I know the Audible Magic CopySense box does not exist as a
product you could get or expect to do anything for you for 10 years.

There's a major decline in P2P traffic on the internet after 2010 ,
and privacy and encryption features' use in internet protocols has
greatly increased since then such as websites using HTTP/3,
TLS1.3+ESNI, or DNS over HTTPS.  Specifically to mitigate privacy concerns
and prevent spying boxes from being run by adversaries on
network service providers networks.

And that is a thing..  there is no passive system a network provider can
use to detect with high confidence a type of data once most users have
figured out you are attempting to block that type of data on the internet:
User practices adapt, and details about the transport method change quickly.


In 2025 you could go to Audible perhaps if you are a website such as Soundcloud
or Facebook needing a service to classify files your users are attempting
to upload,  but not if you are the network service provider who just
routes packets.

The protocols in use such as HTTPS, WebRTC, or  Websockets over TLS
are specifically designed now to prevent you having detailed insights
into those packets.

The same type of encrypted WebRTC traffic (SRTP)  can carry either video
conferencing or IPTV.   The protocol does not identify the application nor the
nature of the traffic anymore,  and both the application and nature of the data
are opaque to the network now.
