You're most likely going to end up having to trawl through millions of applications with no data/info on which to judge them.
I'm also confused as to how this will "get an employer's attention without having to do the recruiting dance." This is pretty much exactly what it's like working with any recruiter. You submit your information to the recruiter, the recruiter contacts companies for you or tells you want available jobs there are and then contacts those you are interested in. From the employers side you have relationships with recruiters who send you over resumes and CV's that are supposedly filtered by relevance and qualifications.
Could you clarify why you feel you offer some benefit over other recruiters to both those looking for work and those looking for employees? So far it seems like you are collecting less information and not doing a skills match which is less than most recruiters I've gotten applicants from have done. For the employee you are saying that you just send on the application. Where is the added value outside of the "I'll accept an offer if I get one" checkbox?
