Resiprofile - matching buyers and sellers

Here is an interesting website, that aims to cut out the middleman (e.g. real estate agents):  See Resiprofile.  I have many examples of real estate agents not returning my calls or emails when I want to buy.  So I move on.  I wonder if the seller knows how hopeless their real estate agent may be.  It is always good to do a "mystery shopper" experiment on your real estate agent.
