Load balancing with nginx and dynamic dns

Hi. I was curious whether anyone has attempted to use nginx HTTP 
Upstream Module (load balance) using named server instances with dynamic 
dns as opposed to ip's. I have heard of pound being used but thought of 
the nginx module recently which should also be easy to configure and 
also reconfigure to potentially add application servers without stopping 

I am hoping this may be useful in an Amazon ec2 context with nginx as 
reverse proxy to multiple application servers identified by name and 
port. There are few providers out there that can provide a short enough 
ttl and where an api exist to communicate with the dns host to modify 
the dns record on server startup or shutdown. Many thanks.
