Where to host docs?

I'm working on some preliminary sqlpython docs using Sphinx, which is really really nice. No guarantees that they will remain there, though - they need a home without a raw IP address for a URL!

I'm trying to figure out a permanent home for the docs. Here are the possibilities I know of.

• Host the files on my own server. Buy a domain name (but not like last time). This is obviously the best option... unless I ever decide to quit paying for the domain, or the server, or forget to, or get hit by a bus. So really, I'd prefer something that wasn't so dependent on, well, me.
• Sourceforge, Assembla, Google Code, and probably everybody else who hosts projects also let you create and host wiki-style documentation. As far as I know, though, there's no way to upload Sphinx documentation into any of them; the wiki form and the Sphinx form are not compatible.
• Google Pages gives you free webpages with a reasonable URL - but no folders. Sphinx depends on a folder structure - it creates folders "html", "doctrees", "_sources", "_static", and maybe more once I get serious.
• Creating a Google App Engine to host the docs - now this is an intriguing possibility. I'm going to check it out. Still, it would be nice if posting the docs for a technical project were not, itself, a technical project.

Any possibilities I'm missing? A convenient way to host Sphinx docs, freely available, would be a really nice service to FOSS developers. I wonder if the Google App Engine approach could be extended to provide that... hmm hmm hmm... just what I needed, one more project...
