Comment 4 for bug 688289

Is there any chance you could offer a patch to change this behavior? I like the idea but don't have the time to change it.

Also, in Drupal 7, it's easily possible to include an external style sheets and seems to work pretty reliably. Any chance you could see how it's being done in the D7 version and tell me if it works any better?

The only issue I see with downloading the file is when it's updated and needs to be downloaded again. There's no cron hook for themes to even check that the file has changed.
