Hi all.

I'm David Ascher, from Mozilla, the new lead for Thunderbird and mail-related activities (including calendaring and address book features).

I'm trying to catch up on the state of CardDAV, and I figured this might be a good source of information.

I know of some Thunderbird-relevant CardDAV work (See SOGo connector http://www.inverse.ca/english/contributions/sogo_connector.html), and I know that Cosmo and SOGo are both servers with at least some CardDAV support, but I don't know much about other implementations (either server or client), or the details of even those servers, such as:

 - degree of compliance with spec
 - scalability characteristics
 - general state of affairs

I'm not even sure I know where the spec is at in terms of finality.

Education welcome!  I'm happy to coalesce all of the info on a public wiki page (e.g. <at> wiki.mozilla.org) if that's helpful to folks.
