Hmm as I’ve recalled to use 7D commander with Di866 requires a firmware update but that does the trick. This is what I’ve read others say during the research phase of my Di866. I have not updated my firmware nor have a 7D to verify this.
The Di622 is only triggered optically, so rule it out.
I'm not sure about that. To prove that it works, you need to test it out with the updated firmware. For me, if it works, I too wouldn't mind settling for the Di866 as it is cheaper. Though said, currently I'm using the wireless function with my 580EXII, whereby the trigger is from 7D's pop up flash.
Do feedback here on your test with Di866 on 7D's Speedlite Wireless Commander.
