integrating Zoho Calendar

integrating Zoho Calendar

Hi,

I currently use Zoho People and recently setup the group calendar. It is a very nice feature that we could use the group calendar within Zoho People.  

I want to find out the following about Group Calendar:
-Any way I could invite non zoho users (like a client) to and event to our group calendar? If that's not available, is there any workaround?
-How I could add the "calendar" into the Zoho People's dashboard or somewhere in Zoho People so that I don't have to click "My Account" and then "Calendar"

Any pointers appreciated.
