I don't believe for a second they'll let just any old person sell their game through steam.
So at best, they allow anyone to use this, but all it does is install the game on Steam after you've sold it through your website.
And at worst, this is just a PR announcement, and really what they're doing is informing all the big shareware makers that they're ready to deal, but all the little guys will be turned away unless they've got something really impressive. And both will likely be handing over a hefty sum (50%) for any games marketed through the service, just like RealArcade.
