Edit events in iCal on Wiki calendar

I know that it's by default not supported, the editing of events from the Wiki calendar in iCal, but still I wanna know if there's a work around.

Does anybody know if there's a work around, coding-wise, programming-wise or whatever-wise, to be able to edit events from the Wiki calendar in iCal?

Now I get a message every time I wanna edit an event that i can't edit it from iCal. But I want other people who sign up to the calendar also to be able to edit the events from their own calendar program.
