 What about adding an anchor/parameters in the URI? Somehow those
positions in the stream sound like "anchors" in a URL.

 As a norm, is not good to encode information in the URI but in this
case could make sense.

 grmph. Well, an option could be to use the URI with
parameters/anchors and write a gstreamer element (a source?) that
understands that URI. Easy in theory, but I am not much into the
Gstreamer details.

 They are interested in some of our changes. It is time to propose our
changes back to nepomuk, but so far I don't know how.
