We've been talking about this for a while. The problem is that the calendar loads dynamically with javascript, not AJAX, so there's no way to frontload it with the list of events other than to just come up with some arbitrary number, say, 6 months of upcoming and 6 months of recent events, and dump them into some mega array. That's a super ugly solution because, well, it has limitations, and also adds a lot of up front load time, having to parse a year's worth of events on every page load.

I believe the solution lies in creating an AJAX based calendar alternative, where every click forward or backward would make a round trip to the server and get the list of events for that month.
