If you spent these time/energy to find a solution to these problems, I think already been created a professional competitive system without stalling, gaming.
Even without Fizzer (I mean using simple google docs files, forum topics, etc.), and I am sure if this system would become successful, Fizzer give puplicity and other help for it.
The system actually in use in realtime ladder showed TrueSkill solved all problem.
I hope when fizze will make polls most of player will vote trueskill with no expiration.
Problem solved.
