Very keen in getting involved with this. I know WP pretty well on the 4.1 alphas right now. BuddyPress 2.1 beta just past and about to try and break 2.2 beta1. Been coding a long time. I feel it will be insecure with out a lot of care and attention though. You got my email and one of my test sites, come say hello. Sorry in a mad rush to get some wine. Greetz :)
