How can the new MobileMe cloud calendars be published locally?

Question

I tried upgrading to the new cloud-based MobileMe calendars twice before the forced upgrade date. Both times I was disappointed (as I was this time), because floating timezone events had their times shifted as though I worked for Apple (i.e. to Pacific Time). This is a bug which will just waste my time.
This is a question about something more pressing.
In the past I could publish my iCal calendars locally so that I could put them on a page accessible only to people inside the place I work.
On one of the previous upgrades, I checked that publishing locally still worked. The solution was not obvious, but it it did work: I could change the location of the calendar. Here is the solution in full:

Now when I try to use this solution, I see that the change location menu item seems to be permanently grayed out for calendars under my mobileme account. Does anyone have a new solution?
Here are some things I looked into without finding a solution:
Using symlinks to pretend the calendars were on my web server at work. The new calendars appear to be in one huge cache.
Looking in AppleScript to see if I could periodically export the .ics files over to the webserver. The dictionary for iCal is far too limited for this.
I could manually export .ics files as needed, but this is both painful and open for error---I really need an automatic solution which does not rely on having everyone at work pay for MobileMe.
Help!

OK...after better keyword choices I did find that the 'change location' solution does work, but only if the calendar is first shared with the world, and then has its location changed:

Does anyone know if information in public calendars can be found in nefarious ways (like by Google)?
FWIW, I did try sharing privately to just myself, so that I could then subscribe to the calendar on the serving machine and push it out as a .ics file...but I cannot share a calendar with myself. Boooo.
