"When we looked at synching before, our (main) stumbling block was that most calendar entries originate as meeting invites that are in people's emails. You've stated that this module isn't being built to handle that direction, but since you asked for feedback that would be my main comment. If double-entry is still required then at the very least it means some way to avoid duplicates of those entries in my calendar when I pull from civi."

I should let you know this module is being replaced by the CiviCRM-native extension here: https://civicrm.org/extensions/civicrm-activity-icalendar-feed

Considering this, and the age of this issue, I'm marking this as "won't fix" since it won't be fixed in this module. However, I've referenced this issue in a new github issue for that extension; if you're still interested in this functionality, please comment on the new issue, here: https://github.com/twomice/com.joineryhq.activityical/issues/6
