For my blog, static files (anything stored in an app's "static" directory, basically[1]) the like are handled transparently through django-storages' S3 support [2]. (The STATICFILES_STORAGE option in settings.) If you’ve used Django's staticfiles framework before, it’s pretty much plug-and-play.
For more dynamic file storage (say, using FileField or ImageField in a model), I believe django-storages would work, too. (Make sure you configure django-storages with the DEFAULT_FILE_STORAGE option set to S3 also.)
Assuming you’re managing your site via a local dev server (or a server that "hosts" the "hot type" version of the site), any time you "upload" a file to your local server, it'll actually upload to S3 (and any calls to "field.url" will actually map to the S3 URL). Not sure how well it'll work in all use cases: I haven't actually used FileField or ImageField myself in the django-medusa+django-storages usecase, but I have used both separately so I’m fairly sure this is possible.
This is a pretty darn good question though, so I’ll likely make a follow-up blogpost with a more comprehensive walkthrough regarding handling staticfiles and FileField/ImageField. Sometime in the near future.
Multiple sites/subdomains is a bit more complicated. I’d say you should probably use separate Django instances for each and render them separately. (For S3, you’d need to use separate buckets, anyway.) If they need to share data, you can configure multiple Django settings.py configurations for each site but still use the same source tree and local database. (See the Django sites framework: [3])
