xiphmontIntra paint is not a technique that's part of the original Daala plan and, as of right now, we're not currently using it in Daala. Jean-Marc envisioned it as a simpler, potentially more effective replacement for intra-prediction. That didn't quite work out-- but it has useful and visually pleasing qualities that, of all things, make it an interesting postprocessing filter, especially for deringing.
Several people have said 'that should be an Instagram filter!' I'm sure Facebook could shake a few million loose for us to make that happen ;-)

Couldn't the images be encoded progressively and adaptively to the content (and gain some advantage)? Rectangle blocks aren't really a good representation of reality. (Unless you photograph a perfectly aligned checkboard pattern)

Daala can't encode rectangular blocks well, no matter how they're aligned.
