[kronolith] WebDav and CalDav

[Gonçalo Queirós]

Hi there. Im new to horde platform. In fact I'm starting to have some
contact with it, because I'm doing an internship in a company that wants
to develop some features to Kronolith. 'm not posting any error or bug,
but instead a doubt. Sorry if its too dumb...
I started to investigate the WebDav and CalDav (although i don't know
none of the protocols, i know what they do).
I've seen the roadmap of Kronolith and i saw that it already supports
WebDav as a server, but not CalDav and none of them as a client.
My doubts are:

Being a WebDav server allows Kronolith to be read/modified by clients
like Thunderbird?

And google can't read/modify Kronolith calendar because google itself is
not a client?

The difference between CalDav and WebDav server is the way how they
handdle calendars? I mean, WebDav will export all the calendar and
CalDav only the changed events? Is that it?

Being a CalDav/WebDav client means that i can read/write google's
calendar with Kronolith? Basically, Kronolith will behave like
Thunderbird right?

Sorry once again for a newbie question, but he all need to start
somewhere ;)
Thanks
