Unfortunately, I believe both Google Calendar & iCloud require secure
connections (SSL/TLS; HTTPS) to speak to their CalDAV interfaces. In
addition to that, while IC/VC supports iCal/ICS file format which the
CalDAV service is built upon, it doesn't actually support the rest of
the WebDAV/CardDAV side of the protocol.

While I haven't tested the import/export functionality of NCX myself,
it does support importing & exporting of Dates data, but not actual
synchronization functionality that you're looking for. You could
probably use it to perform a "manual" sync in much the way that I used
to do with IC/VC & Bluetooth (using Blunt & a PICO Card):

There was NewtSync, but I don't believe it's been updated for
nearly--or possibly even a full--decade at this point. It wouldn't be
compatible with modern calendar apps like iCal.

All that said, I haven't checked in a while, but you may be able to
subscribe to a non-HTTPS version of a Google Calendar calendar using
IC/VC. Also, Google does have an API for Google Calendar, so someone
could write a proxy service (or maybe someone has for other platforms
without HTTPS).
