Correct.

Cool!

You mean iCalendar events, not vCards, right?

Connection info, probably (though a tad messy); open connection, no.
Though... ah, I think you could. We might just have to tweak the
imp/authenticate() method a bit, and/or add an imp/getStream() method.

We definitely have FTP support (see the Horde_VFS library). There is a
desire to add DAV support to VFS, but it hasn't been done yet.

There is already (at least rudimentary) support for this - take a look at
Moment.

Look at kronolith/invite.php. Most of this is already implemented.
