This is a pointer to a blog I wrote for the AskPFEPlat TechNet blog (http://blogs.technet.com/b/askpfeplat/) covering pretty much EVERYTHING UNDER THE SKY in relation to MCA (or MaxConcurrentAPI). This just happens to be one of my areas of sick passion, and the blog pulls together my personal experience along with information from multiple locations online from TechNet, blogs, and support articles.
WHERE CAN I FIND THIS SUPER COOL RESOURCE?
