Answer 1

I wrote a wrapper storage backend around the one provided by boto

myapp/storage_backends.py:

import urlparse
from django.conf import settings
from storages.backends.s3boto import S3BotoStorage

def domain(url):
    return urlparse.urlparse(url).hostname    

class MediaFilesStorage(S3BotoStorage):
    def __init__(self, *args, **kwargs):
        kwargs['bucket'] = settings.MEDIA_FILES_BUCKET
        kwargs['custom_domain'] = domain(settings.MEDIA_URL)
        super(MediaFilesStorage, self).__init__(*args, **kwargs)

class StaticFilesStorage(S3BotoStorage):
    def __init__(self, *args, **kwargs):
        kwargs['bucket'] = settings.STATIC_FILES_BUCKET
        kwargs['custom_domain'] = domain(settings.STATIC_URL)
        super(StaticFilesStorage, self).__init__(*args, **kwargs)

Where my settings.py file has...

STATIC_FILES_BUCKET = "myappstatic"
MEDIA_FILES_BUCKET = "myappmedia"
STATIC_URL = "http://XXXXXXXX.cloudfront.net/"
MEDIA_URL = "http://XXXXXXXX.cloudfront.net/"

DEFAULT_FILE_STORAGE = 'myapp.storage_backends.MediaFilesStorage'
COMPRESS_STORAGE = STATICFILES_STORAGE = 'myapp.storage_backends.StaticFilesStorage'
