I think my biggest difficulty is that I'd like to be able to look at a duration of time and determine the events within that range.

Pulling raw iCal data over HTTP is possible but if you say, set up a recurring event several months back, you need to fetch that original event (even if it recurs every day) to include it in your calculations... I'd love a self-hosted version of this Nylas API [0] for example.

We’ve working on this for one of our side projects. When you have hundreds of calendars and need to find availability for some of them on a timeslot, or fetching the slots for a period of time (I.e, a week) it becames hard really fast.

We are evaluating if it may be interest on it to release as a separate SaaS.

You can find my email on my profile if you want to discuss further your needs.
