I will try, don't hold your breath.
Even without my additional problem of having to go through a gate, it
looks as if the scp file tranfers have only been implemented for
copies of sage (sage0.py, which is the only place scp appears), not
for a general expect interface (see line
eval_using_file_cutoff = 0 # don't allow this!
in expect.py)
In some sense that's enough in most cases (you can have a situation
where exact-same-version SAGE's do all the communicating, and each
runs different CAS on different machines), but there would be another
extra overhead and one can not always install sage on remote.
