just a quick followup: we got the funding.
therefore: if there is anyone who can program in c/c++ or python who
would like to be the recipient of donations for working on libre
source code that will actually end up creating real silicon, with
skills in assembler, HDL, compilers, formal mathematical proofs,
kernel driver development or simply an attitude to learn whatever it
takes to get the job done: do get in touch.
time for us to say "we don't need permission to own our own hardware".

> Yes, really: 180nm ASICs only cost around EUR 600 per square millimetre, and with around 20 or so mm^2 it is completely within the realm of possibility for an NLNet Grant to fund a test ASIC. With each square millimetre being around 40,000 gates in 180nm, that's around 800,000 gates, which is enormous.
> We would then have a proven ASIC, and moving up to 40nm or below, which would require around the USD 2m mark, is a far less risky proposition.
> The irony is that whilst these funding proposals are quite easy to write, we also need to find people willing to do the work! In particular, we need at least one EU Citizen per project. They do not have to be permanently resident in the EU, they do however need an EU residence. Yes this includes the UK at the time of writing.
> This is an extremely important strategic project that puts you - software libre developers - in the driving seat of modern technology instead of picking up the reverse engineering crumbs that fall from the Corporate table with at least a 2 year delay.
