Google Music Scan and Match

So I was rather excited to hear that not only was Google Music coming to the UK on November 13th, but it was also coming with scan and match. My internet plan is not quick enough and does not allow for enough usage to upload all my music files so scan and match was going to be fantastic.

But it isn't there....

Google Music is there fine and although I haven't bought any music yet it seems like it would work OK. Just wondering if anybody else in the UK or you guys in the US have this yet? And if so how did you activate it.
