Creating An iCal Event, Without Creating A Calendar

Question

I am using the iCalCreator class to create an event for user to load into their personal calendars. Here's the info, for those unfamiliar with it: http://www.kigkonsult.se/iCalcreator/

Using the documentation, right on the homepage, I'm able to create an event and output it to the browser. No problems. The issue is that when it is imported (I'm testing on Outlook, but I'm expecting this to persist to other calendar software) it imports as a new calendar, with one event in it. I want the event to go right into your regular calendar.

Does anyone have experience iCalCreator and know how I can make this happen?

Thanks
