Open source software is of increasing use in embedded systems. The GNU General Public License (GPL) version 2 is one of the most popular licenses for free and open source software, including the Linux kernel. On June 29, 2007, version 3 of the GPL was published, clarifying some aspects of the v2 license, and adding clauses to deal with consumer products, web applications and patents.

In this white paper, we study the impact of the use of both GPL v2 and v3 in consumer products, and how using secure virtualization and the Trango Hypervisor
technology can help product manufacturers comply with the GPL license while protecting business-critical Intellectual Property and system behavior.
