From As Yazilim:
Same Office is a simple chat program that automatically detects the computers which runs the same program in your local area network, and allows you to communicate with each other instantly.
For example, suppose you have two computers in your home or office. If you open this program on both computers at the same time, you will be able to chat instantly with each other. You can also use this program to share files with family members in your home or workmates in the office.
