My feeling is that you'd do extremely well if you focus on employee liquidity. I don't think that's your focus or overall vision but a well working and trustworthy place were employees can sell their options hassle free and not get slapped around with all sorts of taxes and fees seems to be missing. That market might get invalidated eventually if startups change their option strategies (YC provides good advice) but it seems like a great initial launching spot to grab some early adopters.
