Get contact of another Mac

Hi everybody
Is it possible to get the contact of another Mac on local network
Kind of ( system.AddressBook ) on network
i need to retrieve contact info of all mac on my local network to compare and clean up
Just need to read once… (not write back)
And make my own XOJO contact book from it


Write an app which runs on those Macs and sends the contacts to master app.

Forum is not only for coding
Point of view is also important too
Thanks Christian
