I would call it "buffer" or something. Proxy has a bit different
meaning I think.

Defininatelly dumping to file should be controlled by parameter. And
also maximum RAM buffer size.

Idea is interesting, but I think it would be worth to make generic
protocol that covers any other, not only live streams.
In some cases user may take advantate of buffering some possibly slow
protocols (like http, ftp etc) that are seekable anyway without
buffer.

Anyway, that are just my remarks. I believe there are people that have
much more to say than me.
