A file-like is a python-esque idiom. You can pass it to all kinds of 
things e.g. JSON parsers, XML parsers.

What if the body is a 1 gigabyte string? Do you want twisted to read the 
results in from the tempfile, instantiate a python string, and probably 
get killed due to an out-of-memory condition?

I vote for the file-like.
