Forum .LRN Q&A: Access ICal and show it in an openacs calendar?

Has anyone done work with ical-files which are read (not imported manually, as this is possible in the calendar package) by openacs and displayed along with any openacs calendar.

What we want to do is:
Create a new calendar and not manually add items but access a ical-file from a remote site (like google calendar does). ie. http://scc.selingers.com/temp/scc2icsv2.php?schulnr=101418
So that we could merge these external calendar in openacs. (editing not possible, of course).
