Depending of price two of these on a bracket may be a lot cheaper than a Canon Macro Twin Lite MT-24EX Flash.
Can it be used as a slave to a 580EX II ?
Maybe Flash Zebra can make an off camera cord with two heads so that it retains full ETTL from the camera menu and could drive two units as though they were one. I wouldn't think that would go so far as to control them individually though, so that might require using a neutral density filters on one side to set ratios. I thought I had seen a two head "off camera cord" that retains full ETTL for normal Canon flash guns somewhere before now.
These might make for an interesting option with a longer split cord. Two of these babies with ratios set by ND gels would be very spartan, but also very tiny. It might have a place in an ultralight/ultrasmall (non-pro) kit. That will be interesting to find out. They could always be paired in close proximity instead of spread out to double the output for a single light source too. Opens up some real creative possibilities in a tiny kit if it's possible. Would have been nice to have even the most basic of controls on it, but for what it's been designed for it actually looks like a pretty cool way to go.
Shoot, if one's going to set ratios with ND filters anyway then it would already be acceptable that one would light at full power while the other was dimmed with a ND filter. That's nearly the same thing as firing them off camera with any old triggering device. Essentially a manual mode in a cave man/spartan sense by blocking light to control ratios. I presume that if they were fired from a trigger that they would still work, they would just default to full power. It wouldn't be "much" light, but it could be passable for the kind of things one would have an emergency kit along for.
