Why is it an error? In python-shell-send-string, (buffer-file-name) is
finally passed to python's compile function in __PYTHON_EL_eval or
__PYTHON_EL_eval_file, and is just used for run-time error messages
according to the docstring.

   The filename argument should give the file from which the code was
   read; pass some recognizable value if it wasn’t read from a file
   ('<string>' is commonly used).

I think it is suitable to use a remote filename or even buffer name as
long as it helps Emacs find the source.
