You want to make a transparency pool. This is not a breach of privacy because people want the transparency when they sign up to your pool. It's a sign of quality and a particularity of you pool like other have other things like no fee, a kind of paying, an API feature, etc.

I think all your ideas are good, the more the pool is transparency, the better is for all users and for promote your pool. I have essentially signed up for the very good GUI, dedicated miner and the performance (more than phatk tweaks and poclbm, need more stability on the other side..). But if you make full transparency for your pool, that will be awesome!

(And please, I know there isn't a priority, but do anything for the poor CPU like at my work, and like a few people working with poor PC) :p
