ATMega8U2 VID/PID etc

Would it be legitimate for me to make a product that includes the ATMega8U2 running the firmware from the Arduino UNO, unmodified, and sell it? Or would I have to also go off and purchase my own VID/PID? This topic seems remarkably complicated in my cursory background research so far. I'm hoping I can get some straight answers and discussion here!

Are you building an Arduino derivative?

Considering it, trying to figure out of the USB thing is a show stopper...

Does this help answer your question...

The two paragraphs containing the word "derivative" seem to be relevant.

Or this...

There is a discussion here about the USB IDs..

This may be too old but it should give you a feel for the Arduino developers' intent...
