Thanks for the detailed answer! Open hardware is something that not
many understand at the moment, licensing or otherwise, and the methods
or practices from software cannot be applied directly. I'm happy to
have again learned a bit more.

Sounds excellent.

Yes, there is no immediate benefit even freedom wise to have
everything under a free license, if it doesn't fit the big picture.
With small resources, some control over things is also useful... also,
the freedoms as such don't bring new development, if there is no

One interesting aspect of hardware to me is that it's so much more
"non recyclable". It's not just something you can improve over 10
years to perfect, but for example GTA02 components are simply not
available anymore. I guess this won't change until RepRaps of the
world can really reproduce any component from scratch with
dpkg-buildhardware. Until then it's probably most useful to perfect
the free toolchain used to design hardware - a bit like gta02-core
aimed to do and furthered.

Anyway, starting to go off-topic too much :)
