I am the developer, and I can prove that this is not a scam. You can download
the cd56.iso (without source) at http://www.libertybsd.net/cd56.iso
It doesn't contain the sets, so you won't be able to actually install a
working system with it, but it does contain the installation scripts. Check
/etc/firmware and you will see that no non-free firmware has been included.
Now that I've proven that I actually do have the system, can I ask that you
please support it? Compared to other projects such as the Librem Laptop [1],
which will be released once $250,000 has been raised, I think a price of 3BTC
is quite reasonable.
Also, if you make a donation, I might be willing to send a CD to your house,
or let you download a pre-release version. Contact me for details:
