1. A published iCal calendar
2. A file attached to an event within that calendar in iCal app
3. The attachment does not show in the published calendar in web view
4. Why? What's the missing piece needed for the file to show up and be downloadable?
Attachments are kept on your local machine with just a link in the event. I don't think there is a way to have them upload with an event and be downloadable.
Professor Hubert Farnsworth: “Nothing is impossible. Not if you can imagine it. That’s what being a scientist is all about.”

I've read a few (very few) posts about it's existence, but
no how-to and the Published Calendar options indicate that
it can be done.
