I find this question very interesting... But I am guessing that you don't
have many allocation possibilities, especially with a small number of 
factions.

Another thing: I guess it wouldn't be cloneproof. Say there's normally
only three parties and everybody votes for a party list. I guess a
party could gain an advantage by running two lists instead of one.
