That's a good question. I haven't thought about those kind of issues.
Delegation is much more complicated than I thought, even for this
"simple" case. ;-)

The main issue is how to reveal information about delegation for two
kinds of votes :
- vote as a participant (private, void if the participant has
delegated his vote);
- vote as a delegate (public).

Unfortunalty, the two kinds of vote are interweaved and have effect
one on the other (as you are pointing out). I currently don't have a
clear picture of the issue or even of what it is necessary to have.

I don't think so.
