I don't have exact numbers off the top of my head and it's extremely
complicated to figure out. There are a lot of nuances you won't remember to
factor in. I could spend the time on this or I could spend the time working
on getting out another free software friendly product, like say, a wireless
router.
We're in the process of getting a new wireless router out the door with
Respect Your Freedom certification. However it's complicated because there
are no free software distributions that run on modern inexpensive routers.
That means we have to spend time developing a new distribution, testing, and
getting the router itself RYF certified.
For those who weren't at Libre Planet 2014 we're working on a new
distribution called LibreCMC that is 100% free software. Similar to LibreWRT,
but modern, and will run on numerous less expensive routers. Currently we
have 4-5 tested. We will have one of these routers certified and readily
available purchase flashed and tested with the new distribution.
