Ipaper / Scrib d is now blocked in China :(/ Can anyone tell me an alternative to use in China?

http://embedit.in/ is similar - no drupal integration, although it does have an api if you are ambitous.

Actually I recently created a module that is based on the Ipaper module but for the Embedit.in service. It can be found here: http://drupal.org/project/embeditin

Currently it is awaiting full project status approval by the Drupal moderators (or whomever takes care of this). This is my first publicly published module (I have made many non-published ones before). Please take a look at it and let me know what you think.

This module has been tested and put to use on a client's internal site (so I am not allowed to reveal it to anyone unfortunately). But it works just as well as the Scribd one (though with less features).
