Yes. I prefere to ask the WEB or RV server about the live content, using normal IP addresses (DST and SRC), normal DNS, normal URL's. etc. Then, if my request was catched by the _on-the-fly-cache_ or _on-the-fly-repeater_, it can propose me (my client) to use multicast (xx.xx.xx.xx) instead of unicast data stream. My client can aggree or disaggree. The replicator can not propose me multicast, multicast can be unreachable, etc. If MCAST is ONE-OF-A-FEW-OPTIONS, why not? This days, when your NETSCAPE request something by http, it send _the set of possible encoding_ and some other _possible options_, and it's doing transparently for you. We have a lot of GREAT multimedia clients and servers this days; some of them can use multicast as one of the options; and we have a global, stable, well hierarhied (L2, IP, TCP, DNS-names, HTTP-names, HTTP-like-requests) Internet. If you start from this, and use MCAST in some cases 0 why not. But if everyone ask me _do you want to read this doc? Please, install China fonts and learn China language_ - sorry, I better search something else (I do not know China). On Tue, 5 Oct 1999, Charles Sprickman wrote:

Caching doesn't work for live content.
Why? (And what is "live content"? You mean interactive? Or "live" TV coverage?)
And wouldn't a cache box with multiple people watching "live content" basically bring us right back to multicasting? One stream to the cache operator, multiple streams out to the clients... Multicasting.
There's at least one commercial service that does this with RV and NetShow.
