CloudFlare was actually very encouraging. I emailed our internal open source legal mailing list and had responses from our CEO and Head of Product Strategy within 5 mins that were really excited about it. There was a brief concern about phishing, but that was quickly resolved. It was more difficult writing the blog post than getting legal's approval :P

This is fantastic! I am really happy to see open source
stuff from www and would love to see this open sourced soon
with a nice blog post describing why we wrote this, what
the transition was like, what the components do.
We've done a tremendous amount of blogging and open
sourcing of systems level stuff and it's great that we can
do the same here. Super to showcase all our technology.
Really nice.
But, oh, those guys reply and that's what you remember?
Wow, I'm jealous. Every time I've tried to get stuff open sourced at the company I'm with I get blocked by legal usually they just don't get what the technology is, like kernel bypass PF_RING network processor :( one day. Glad to hear you had a good experience though
