Come to XPSD on October 1st where I will share my ideas and experiences gained while in Shanghai.  I am not sure if I will turn my presentation into a post, but I will give away my key point now: you will have much more impact improving the performance of your Scrum teams by providing soft skill training to the ScrumMasters rather than training on hard skills, i.e. estimation, Planning Poker, Scrum mechanics, etc.
