I have tried owncloud on my local server, and on a shared host, and ran into
a lot of bugs (I opened a few on their bug tracker system). Most problematic
for me, was losing access to my calendar after an upgrade. I must say I
don't trust owncloud to host my data in the current state of the product.
Replacing google calendar is more difficult than I thought. I currently use
WebCalendar on a shared hosting, but there's no caldav support.
I tried to setup davical on my home server but it was difficult for me.
Although caldav worked straight away, the lack of a web editor and the lack
of an import/export in ics format was a dealbreaker for me. If those
functionalities do exist, please let me know!
So does anything exist besides owncloud and davical to try to replicate the
Google calendar experience?
