Actually, I did mean RTP (aka RTTP) rather than RTMP. But as I was wrong in either event, that hardly matters. It's interesting that the originators of UPnP chose to use HTTP, as the references I looked up indicated that HTTP is not designed for real time communications, and identified RTP as the protocol for streaming. If I'd started at the right end, and refreshed my memory on UPnP, I wouldn't have been caught out ...

I agree.
