I don't want to induce a lot of offtopic and negatively. The 30 days
in the subject is something that I would like to realise, not talk about.

I do not have yet investigated what the options are of CoralCDN, but
the main problem is to get the *alternative used*. I guess switching
to a system that is partly in our own hands results in a higher
quality, thus we must have ability to invalidate data quickly.

If that is covered in CoralCDN the only thing remaining is finding a
good solution for the 'hostname' issue.
