you can make an 'opposite' service to break exclusivity for example, a site that compares different insurance policies/companies, etc in my case (not from the US), i wanted to sell mutual funds and claim 1% marketing fee :) ... i even passed mutual-fund-manager-certificate-govt exam (just in case, also out of curiosity) to my surprise (6 months and 1 web app later), only bank is allowed to sell investment packages to individuals (for security reasons) so not only i cannot take 1% cut (i'm not a bank), banks also do not want to deal with unproven small fry eventually, i changed my site into site that compares various mutual funds (tables, graphics - love jquery+flot) but alas, most of them performs below the index; so comparing them shows how bad the funds actually are anyway i ended up making it a non-profit site ... users love it and i got various feedbacks applicable to my other web apps
