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 ...

Thanks for this pointer. It seems that RTP plays a similar role to Linn Songcast with support for multicasting and real-time delivery of audio packets. In contrast, UPnP streaming normally uses buffering in the renderer, which would make the real-time capabilities of RTP redundant for this usage.
