Funny that you choose multicast as an example. I always thought that it is a very rotten idea, and a security nightmare, too. Distributed transparent caching does not require injection of any routing information from customers into the core routing, and is a lot more efficient than multicasting (i.e. you can always think of multicasting as a caching with cache retention time set to nearly zero). > These good practices, of course, have to start at the vendors.
