Obviously, this is still early days. But I have been using this plug in with three separate Tbird addressbooks totaling 10K contacts and 50 labels/distribution lists. And I'm using it in full read-write mode.
Marco has been fabulous in his responsiveness when I report a bug.
Note that for really big addressbooks, the sync may take 5 minutes or more in full read/write mode.
