Mieru, my other Python app is already using Clutter for a part of its interface. The speed is OK and I have not noticed any Clutter related crashes. So basically I have all the needed tools - now I just need to sit down and start writing the code.

I have also developed custom kinetic scrolling code for Mieru, which should be also usable in modRana to enable kinetic scrolling for the (Clutter accelerated) map screen. Another use could be for Hildon independent kinetic-scrollable lists.
