Well, you're right. But there's nothing special about gif per se. Gif happens to be both a container format and a picture codec at the same time. Handling animated GIFs in that regard should be no different from handling AVIs with MPEG4 in them. Although Plan9 file model, as nice as it is breaks horribly when we start talking about HD multimedia content. The performance bottleneck is quite noticeable at 50MBpbs :-( Thanks, Roman.
