[c-nsp] Two Cisco 8xx, point to point multicast??

I have a friend who has been gifted with two new Cisco 881s and strict orders to get multicast flowing between two locations using a GRE tunnel. We're happy with our IP routing, tunnel protection won't be a problem, but it's been forever since I touched multicast and these things show no signs

BGP requires memory to store routes. The 2610 maxes out at 64 meg. The 3550 is hardwired with 64 meg. They're equivalent in terms of storage space and I think roughly equivalent in processing power. I think a 64 meg box starts to have trouble around 50k routes if I'm recall correctly. If all the
