I go to a website which I access with my Dropbox credentials.
A list of my folders shows up. I click on the checkbox next to the My Website folder.
At the bottom of the page, I click on the Make Public button.
A dialog appears, confirming that I want to give this folder a public URL.
Once confirmed, a dialog appears giving me the URL.
I'm not sure. It could be a server itself that does real-time caching of the contents of this folder. When a request comes in for an item in the folder, it does a HEAD request on the file, if it hasn't changed, it serves out of its cache.
Or it could keep the contents of the folder in synch with a folder in an Amazon S3 bucket, or some equivalent service that runs the server that accesses the content.
It could be a for-pay service. I would happily pay a few bucks for a year's worth of set-and-forget web access.
And for a few more bucks, a custom domain.
Super-lightweight post-Web 2.0 web hosting.
The CMS lives elsewhere.
It just serves up the content.
I want to build on this feature in my software.
