Recently this got produced as a draft license for parties distributing 
CAcert's root certificate(s) (like us).

https://svn.cacert.org/CAcert/Policies/Agreements/3PVDisclaimerAndLicence.html

This is still in draft hasn't been discussed in CAcert's policy group yet.

If you want to follow/contribute to this discussion look for a post to the 
policy list soon.

I make no inferences good or bad about this. Mainly because I'm writing this 
with a headache.

Cheers,

Daniel
