Nah, I kid. What do you mean by "colonial size"? To me, a colony could be a dozen guys in a habitat on the surface of some interstellar rock. Do you just mean that there are no Caz in positions of power or in sizeable populations on colony worlds?
On another note as H2.0 is a subculture, it's rather open. There are 'Type 3' Nakeesh running around, would there also be 'C2.0', 'P2.0' and 'Z2.0'? (Caz 2.0, Pleocygrans 2.0 and Zodohaani 2.0 respectively.)
