It would be great to give people the option of what kind of calendar they will be downloading the invite to and have the invite formatted/downloaded accordingly. Right now if you download the existing calendar invite it is in .ics format which is great if you use Outlook. But for those that use google calendar, you have to have the extra step of importing it into calendar. I have seen several sites recently that give the user this option and it's very helpful and better user experience.
