In general I don't need board updates, because I'll post one after each of my moves. So I would either upload your board, or update my copy with your move, and either way is about the same time. (The time control comment for you is about possible live play version, right)?
My move:
7...B(3,8)-(7,4)
lol. You made me realize that maybe some games should be played with a different time control other than 3 days. Maybe a game with 1 day per move? Or players have a "bank" of time, like 10 days for 10 moves. If you get ahead by playing fast (like you are), you have more time later when you need it. It hasn't been discussed much, but I wouldn't mind trying other time control methods.
You are suggesting that a live time control be enforced on a daily game. It can work. However, I want a daily time control enforced on a live game (15 seconds only each move, with extra time thrown away.)
