Are there any cheap routers with multicast (IGMPv3) support out there?

Oh cool! I have not seen the multicast / IGMPv3 option in dd-wrt. Must not have looked closely enough. I'll check it out. Thanks!

Oh awesome! How come they don't mention this in their specs?! Maybe I didn't look closely enough. Thanks!

Oh, one question though. When you say multicast is supported, do they also run router-router protocols to exchange route information to build multicast trees? Or are we talking about IGMPv3 on the client side, and forwarding to next hop only?
