The main page for python says you can just use - for the filename for 
stdin.  But:

$ python -

seems to go straight to the interactive interpreter.

However

$ cat - | python -

definitely works straight from stdin, as if it was reading a python file.

This all seems like a bit of a hack, but the following fabfile.py seems 
to work for me:

-------

import fabric
from fabric.api import run

pycode = """

# code to be run on remove server(s)

import os
print os.listdir('.')

"""

cmd = """python - << EOF
{pycode}
EOF""".format(pycode=pycode)

def runpycode():
     run(cmd)

-------

Adjust pycode to whatever you want.

Cheers,

Rasjid.
