How to integrate Writer with my site?

Hello.

Is there some way to open doc document with Zoho writer from my site?
There list list of docs on my page (links to files). Can i allow somehow for my site visitors to open that document with writer by simple click.
Example, to put spiceal link near file "View with Zoho" . When visitor clicks on the link new browser window is opened and document is autoimported to zoho.

I think my visitor must to be registered in zoho . And the visitor must enter login/password after he click on link(button) on my site.

Has zoho this feature?
