How to integrate a Google Docs document in Liferay?

Is there any way that we can integrate Google Docs in Liferay? I found some other 3rd party APIs, like Zoho, but I would like to use Google Docs instead.

may be, you cat sync google docs with the server by some tools like here

and then you can sync this desktop folder with liferay
