I don't see a problem with your design - proxies caching for a period
works for me. Datasets being correct up-to-the-minute is nice, but not
essential, since they don't change that often.

I have added the 'Alter: Cookie' header to DGU to avoid problems with
public caches when the user logs-in.

BTW It would be useful if headers like this could be configurable in
ckan, without having to monkey patch.
