I've been using something closely modelled on that Cookbook recipe, 
without any real problems.  (I've updated it to use HTTP[S]Connection() 
and return the response object, and in my case I'm connecting to an 
HTTPS server, but these are trivial modifications.)

I, too, was surprised that the existing Python libraries don't directly 
support multipart/form-data already, and I hope that this gets added in 
soon.
