Membership and Google Checkout

I recently signed up for WPMU specifically to get the membership plugin. I thought I had verified beforehand that it supported Google Checkout. After installing it it appears this isn't an available gateway. Am I missing something?

Can't imagine a reason for not having it. Saw something on a thread here that it's not supported because Google doesn't support recurring membership. This is old data from 2009, they do support this now.

If not can anyone suggest an alternate?
