What is Nemo and where can I get it for N9?

EDIT:

Ok googled it a bit instead

Found it is a community version (?) of Meego made for N900 and N950 with a N9 port being worked on.

How can one be 100 % sure its carrierIQ free? Because it is open/transparent and made by a community?

For one second let me get my tin foil hat on :P

Is there no chance that CarrierIQ is programmed into the core of the OS and hidden really well even in the Open Source unless removed?
