Not quite sure what you mean there Wheeler. Without and Internet connection you only get live traffic picked up by your box and antenna. With an Internet connection you get the Network Data as well. You can deselect Network data, and you can stop processing hardware (live) flights too (if you do both at the same time, you will see nothing).
What are you trying to do? Give us an example of what you mean.
Keep asking those questions :-)
