For some reason, Chrome settings and autofill data are saved in Google Docs, but the two files can't be shared or exported.
The nice thing about Chrome Sync and other similar services (Opera Link, Mozilla Weave, Google Toolbar) is that you can use any computer and keep your browser's data in sync. Mozilla Weave synchronizes more data: passwords, sessions, browser history, but it's likely that Google will add these features to Chrome. Google could also synchronize extensions and themes.
