Anyone using it? If so is it worth it?

They only control Wowza Flash streaming, on linux servers.. so it has its limitations. Doesnt work with Windows servers, windows media streaming, etc

I would say Wowza supports all except WMV. Silverlight is supported.

By end of the month, we should have all major protocols supported, RTSP, RTMP, silverlight, iOS...

i don't use it while i heard it is not that good!!

but if you must try and tell me the result!
