Having spoke to timplunkett regarding this idea it was suggested to create this thread.

It would be very handy for fullcalendar to have a field formatter. Use case scenario's include for example you are creating a profile page and want to add fullcalendar functionality to a profile. The way to do this would be through using a field formatter to display fullcalendar alongside relevant profile info.
I'm sure there are plenty of other use case scenarios as well.
