Looks fine to me, just two comments:

>         """Wraps the output stream's write method, encoding it with
>         the specified encoding"""

You should check that obj is an unicode object before calling encode.  
Strings should not be encoded.

__getattr__ is only called when the attribute has NOT been found in the  
usual way, so checking for "write" is unnecesary. Just return  
getattr(self.stdout, attr) always.
