Eric, so the JS library doesn't use JSONP in its implementation? Do you know if there are limitations to the size of the contents of an item that can be saved via the JS library? My understanding is (was) that when making cross-domain JavaScript requests, to get around the same-origin-policy, you end up having to pass the request data along in the URL, so you're limited to about 2000 chars or so depending on the browser.
Well, anyway, i'll take a look. God, i just finished a JavaScript interface to the Python libraries to act as a proxy, to get around this issue and now i may not need it - why does that always happen. It's for the best i guess.
