It is true that broadband isn't viable if it requires a high-bandwidth from one source to every end user; the stream has to be exploded at some replication points near the viewers. But that replication doesn't have to be done by the routers; it can also happen at a distributed network of servers, which can be intelligent enough to add watermarking at a cost on the same order of the cost to provide SSL. This sort of server-based multicasting is widely deployed today by Akamai and others, and has been far more successful than router-based multicasting. -- Shields. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
