-- 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
