Cosmo provides a server that implements a CalDAV draft that pre-dates
RFC4791, so for instance Cosmo doesn't support ACLs yet.
Cosmo also doesn't support draft-desruisseaux-caldav-sched, which
describes the mechanisms for scheduling attendees centrally using an
INBOX collection on the server.
Some CalDAV servers currently support scheduling attendees whose
calendar home *isn't* on that server (by sending an iMIP,
iTIP-over-email, requests). The resulting request is handled by the
calendar client out-of-band, not by the client's CalDAV server.
Server federation (akin to SMTP) where servers handle cross-server
requests in-band isn't something supported by any CalDAV server that I
know of at the moment, but I think a spec for federation is in progress,
Cosmo isn't under active development at the moment, but I'm sure the
Cosmo user community would be delighted if someone stepped forward to
implement more of the fast-emerging CalDAV specs.
