I would be impressed with 2 mil lines allright.
At least with an air agitated vertical etcher using CuCl i don't think  
it'll work.

I don't doubt it is possible with the right etcher, they do crazy stuff  
etching ICs, but in my etcher i don't think so.

You are welcome to try, and i'll be appropriately impressed if you  
succeed, but it doesn't really matter since nobody needs such fine lines  
anyway.
