The controls (forward and Rewind) can be done, but also depends on your media. Some of your media will not support seek on streamed media, thus no software will do the miracle, but a lot of formats indeed support it and we plan to support this in future versions.

so indeed there's mediastreamer (that can be both the client and control point) but the media issue still. Canola upnp uses exactly the same UPNP lib that mediastreamer.
