TODO

@ -1,15 +1,8 @@
- implement json http module for accessing stats
* memory stats (shared bufs num/bytes, private pools
* global (connections, IO bytes, bw)
* live (stream name, flags, clients, bytes, bw, drops)
- add global & per-room in/out byte counters
- add per-client audio/video bias
- write complete WIKI docs
- rename netcall to upstream
- global rename: get rid of '_module' suffixes in files && rename netcall to upstream
- add support for flv file streaming
(NGINX supports streaming flvs via HTTP
