I'm wondering of anyone has successfully got a gateway running in Amazon's EC2 service? I was thinking of using a raspberry pi with a tinc VPN to the EC2 instance to tie into my RF connection regardless of my IP address. I hit a wall when it came to getting ampr-ripd running.
It is a bit difficult to help you with such a problem description, but in general (I have no experience with EC2) you should be aware that such services do not give you a fully virtualized machine where you can do what you want, but rather they use Xen Paravirtualization where a modified kernel is running, and it often does not include the module required for IPIP tunneling. That may be the wall you are hitting, but it would not be the problem of getting ampr-ripd running but to actually get the tunl0 interface working. So you need to explain better what your problem is. Maybe it can be worked around using another program by Marius: amprd.
I have a Raspberry Pi running at a hosting company and running the usual configuration for a gateway under Linux, and of course that does not have that limitation. I have a VPN to it from home. Indeed it is a nice way to get a gateway running without the trouble of getting the IPIP traffic to your home system. (but it is not used much anymore as I now have a radio connection to the network)

Actually, EC2 will give you fully independent VMs that let you do whatever you want with the Kernel.
We use EC2 a lot for work, I had never thought of setting up a gateway in it. It would be a trivial matter, just make sure you create the right security profile that includes the IPIP Encap packets.
You will also want to assign an elastic IP so that it's external network address don't change.
If you run in to any snags give me a shout, I may be able to help.
