Ask HN: Multi-streamed video puzzle. How to?

I received lots of comments privately. Basically there are two schools of thought: native desktop app and HTML5 browser-based app.

The former would be done using gstreamer for streaming and encoding/decoding http://gstreamer.freedesktop.org/ , and clutter for the UI / display, http://www.clutter-project.org/ .

The HTML5 thing would be for sure inspired by the work of Alex Wolkov at http://alexw.me/2010/05/html5-video-puzzle-proof-of-concept/ . It isn't still clear to me if I will need the help of the GPU, i.e. use WebGL (Alex doesn't).

BTW it has been noticed that streaming separately the blocks of the video puzzle might introduce sync issues, which is something I still have to figure out how to solve (if will see it as real issue in my prototype -- no premature optimization in my home!).
