"One other thing. The MLS was created and is maintained by Realtors. So please don't compare it to the RIAA."
Not a problem. One pays a fee to belong to MLS and access the data. It's racketeering and collusion for MLS or any realtor to set a "standard" real estate commission fee, let alone enact "penalties" for those who don't comply to the "set" fee.
So with regard to the whining by Realtors against the discount guys, yes they are very simlar to the RIAA.
Say that again?
