Tomato firmware is described as:
"… based on the GPL source code released by Linksys, but includes proprietary binary modules from the chipset manufacturer Broadcom. Portions of the code are licensed under the GNU General Public License, but the source code for the user interface is under a more restrictive license which forbids use without the author's permission."
I am researching the possible use of this firmware in a commercial application. Installed on Netgear 3500L hardware, it would be provided to subscribers as part of a service, and would have one proprietary application installed that was not linked to any GPL code or library.
My understanding is that this would be proper. Full source code for the GPL code is obviously available and would be provided on request.
So my two questions for the forum are:
1) Am I correct in this simple assessment, or should I be requesting commercial licensing terms? If so, from whom?
2) Who is the author from whom I need permission to use the UI, and how should I contact them?
I don't actually need the UI for this application though, so I could just remove it.
Thanks for your advice.
