Wow, their patent contribution stuff should have people running for the hills:
"You assign all right[s ..] in all patents, inventions copyrights and related moral rights ("IP Rights") [..] to SugarCRM[. ..] SugarCRM grants to you a non-exclusive [..] license to [..] Your Contributions[..]"
So, if you hold a patent which touches some SugarCRM contribution you make, you lose the patent and any rights to use it outside those SugarCRM contributions.
I'm not going to defend software patents for one second, but that's a pretty spectacular agreement if they think people will sign up for that.
But then you can probably count community contributions to SugarCRM on the fingers of one hand (I've tried).
