[Remind-Fans] Caldav possible?

[Borghal Rantipole]

hello,

I'm new to remind and would like to know whether there is a possibility to work with an caldav calendar? I'm syncing between different machines and have a zarafa server running, which offers a caldav/ical calendar that can be integrated in different clients. 

I found that downloading the calendar and converting with ical2rem works, but there is no way to send changes back to the server. Or am I missing a great feature?

Thank you for this wonderful software!
