Hah. To look past the obvious reasons that would merit a bwoink, I think that in general the naming scheme would rule out any names containing proper nouns.
Just like with marine names, xeno names would have to have rules outlining what is and isn't acceptable. Either the names are kept short (like six letter maximum) or limited to some scheme like 'Adjective Noun' (ex: 'Slow Turtle', 'Gray Stone', 'Red Dog'). I'm personally a fan of the idea of the single word adjective/noun names that I suggested in the original post, but honestly I can see a lot of naming collisions coming about as a result of that.
