I hadn't tested blink with the no_cache radiosity yet, but yes - from 
the images you sent me, it seems seriously broken. But I have a hunch 
why that is, and if I'm right it should be easy to fix.

No, not at the moment, and in the case of the camera it certainly won't 
be anytime soon - the internal architecture isn't suited to switch 
between cameras while rendering a single frame.

As for light sources, it's probably just a matter of finding a bit of 
time to implement support for blink.

Depending on what you want to achieve, you might be able to simulate 
blinking lights by enclosing the respective light sources in "no_image 
no_reflection no_radiosity" objects that blink just the other way around.
