Some Angels using Investment Readiness Level, should RVI?

Last year Steve Blank proposed a system for evaluating startups usable by educators and investors (our blog post about it here).  Since then the manager of Sacramento Angels put the theory to the test and likes the results.  It strikes me that here in the Pioneer Valley we have an opportunity to adopt practices like this throughout the entrepreneurship ecosystem to provide a consistant language for startups, investors, and partners. What do you think?
