iTunes Match in iTunes?

[rstark18]

I downloaded the beta of iTunes that allows iTunes Match and signed up for a subscription. The sync was painfully slow but finally completed. Now that it's done I'd like to download a Match version of one of my old songs but don't see how to do that in iTunes. Anyone figure out this part or is it only going to be available at release. I know I can access it from my iOS5 devices but I want the download on my PC.
