I have the SyncKolab plugin installed with Thunderbird. I can't get it to work properly. Maybe I have to have a Kolab Server? I can get my Address Book contacts to sync with an IMAP folder when I check Sync IMAP, but I can't get it to work the other way around. From their website, it seems possible:

SyncKolab

SyncKolab was written to add kolab functionality to thunderbird. It reads a selected Imap folder and synchronizes it with the local address book and calendar.
It has been tested under Thunderbird 1 for Windows and Linux. 

What is Kolab?

What it does is, that it loads all your contacts (from a selected address book) as well as events and todos (from the selected calendar), and synchronizes them with a selected imap folder. Where every contact is stored as an vcard and every event,todo as iCalendar. For more information http://kolab.org/
The idea behind this is, that you can now have your contacts+calendar entries stored on the imap server. so you can actually have the same addresses on more than one computer. The kolab project has a groupware server that uses imap to exchange calendar entries and vcards. But you can also setup simple sharing in your office if you have f.e. cyrus by symlinking shared folders.

Yeah, I've explored the Outlook connectors some. Do any exist that are free/open source?

What are you using in Thunderbird to store your contacts+calendar info on the
IMAP server?  The only tool I've found like that is Kolab Sync, which didn't
work last time I tried it. :/

As for Outlook - it's absolutely correct.  You'd need some sort of "Connector"
to translate their Contacts/Calendar storage to IMAP.
