Is it open source? Or closed source like RemixOS/etc (the other ChromiumOS builds) Actually it would be great, if a community project provides binary builds (and source in case of modifications) of Chromium (browser) and ChromiumOS. Building the source takes 16+GB ram and several CPU hours. Sadly, Google doesn't provide the builds (binaries).
