Hey,

We haven't tried this in real-world use cases. But I am sure others
have used RTMFP group, not necessarily with VideoIO

Probably depends on the bandwidths and network locations of the users.
For example, if many people are behind restricted NATs, it won't work.

Using AIR, may be. Not sure how the RTMFP protocol/logic incorporates
mobile devices.

On VideoIO, the liveDelay property could give the idea.

On NetStream there is similar one.
