Andy, sorry, but it appears I was wrong. I just removed my security for a moment to check the RSS thing, and it appears that you have to set up the RSS feeds in the Momento Live account. They are two separate options in the frame menu, so that's why I thought it was separate. Not sure why it wouldn't be. Seems like a pretty easy thing to me...

Anyway, I'm still looking into it, but I can't tell if the Momento account is free or not. It looks to me like it is, but I'm not sure...
