Actually, doing this is quite straightforward. All you have to do is
create a new Python object type that implements a write() method and
contains the ostream that you want to redirect too. When the object's
write method is called, you simply forward the string to your ostream
instance.  The python code to assign an instance of your type to the
python stdout instance would look like:

import sys
sys.stdout = InstanceOfMyType
