I'm really interested in Route 53 support. I haven't had a chance to jump into the code but thought I'd post this issue so anyone else who's interested can collaborate.
I researched that since I'm interested in this service myself. But I did not find the time to actually do it. The Route 53 support can't be added in a straight forward manner. It is a "RESTful" API that doesn't look like the existing query APIs or the S3 "RESTful" API.
I'd love to see Route 53 support, too. :-)
