Adding a new function to the address book in android

Hi, is it possible to add a new function to an existing address book?

What I'm trying to do is add a shortcut to my application just like there is a shortcut for sms in each contact, whenever a user opens a contact, he can see my version of the application there, he approaches it, and my application will start with this contact information, is this possible?

We have options such as a link to facebook, flicker in the contact list, how did they implement this? Can I create a similar thing ??

Can I do this in version 1.6 or does any higher version have support?
