Since I live in Google Calendar every day anyway, it would be great to use that interface to browse my #indieweb events as well! Since my events page is marked up with h-event microformats, all it would take is to write an h-event to iCal converter script to generate an iCal feed from my list of events. Then I could just subscribe to the iCal feed from within Google Calendar.
Even better would be to use Google Calendar to also create events on my site. Unfortunately Google Calendar doesn't support CalDAV, so we can't do it that way. (Of course I could use Apple's iCal to publish directly, but that also means I'd have to write some code tot speak CalDAV).
Instead, I can create a "write-only" calendar in Google Calendar, and have p3k subscribe to it. Any new events in that feed would be moved over to the internal events page and deleted from the Google Calendar.
