This is a huge market and there are lots of competitors out there. Just FYI that 1/3 of the AWS price isn't really considered cheap when you look at the budget market. Some of the cheap European providers have US presence now as well. That said, the pricing isn't too bad and the lineup looks good. Also, the website also gives me issues on my Android phone.
Regarding Comcast pricing being out of reach, what are your thoughts on their low-income program, https://www.internetessentials.com? It's 25Mbps for $10/mo. There are probably hoops to jump through, but it does seem within reach otherwise.
This project is awesome. Do you know if there's a way to bundle up something like a python or PHP script so it runs standalone without needing the runtimes on the target system?
This is also similiar to Sneaker (https://github.com/codahale/sneaker), which is written in Go. It doesn't copy to other regions by default, but it's not hard to handle that on your own. This also uses KMS, but stores encrypted secrets in S3.
I'm a big Terraform fan, but I really don't like HCL and its limitations. I ended up writing a PHP "SDK" of sorts that generates JSON that Terraform consumes [1]. It uses the AWS SDK for some things (like listing all available AZs in a VPC), and provides some macros. I made this for use at work, and it powers a few production sites for a large company.
There's still a lot to do to make it ideal for public consumption (like writing docs and freezing the API), but it'll get there sometime soon. PRs are most welcome.
I wonder if they use IMAP's EXAMINE or SELECT commands when iterating through folders. The former is read-only, although the end user has no control or guarantee that this is how they'll go through folders.
