No -- these are not appropriate for a class, since they could easily go down for
a number of reasons, and they aren't that robust. They are only meant for
people to do some temporary testing sharing of SAGE worksheets -- but shouldn't
be the main way a person makes SAGE available to a class.

It is just as secure as giving out a guest login/password to your machine
for logging into that account, i.e., it's back to the question of how secure
OS X itself is against a local exploit, which is I guess a standard question.
In fact, you may want to have a guest account for your students, to allow
students with ssh to connect and use the command-line version of SAGE,
which some might like.
Regarding how you actually start the notebook server, I use this script (with
the notebook line having no line break):
[EMAIL PROTECTED]:~$ more notebook.py
from sage.all import *
notebook(port=8101, address="sage.math.washington.edu", jsmath=True,
color='gmail', restart_on_crash=True, username="", password="",
auto_restart=800)
---
Then to actually start the server, I type
sage notebook.py
Note that auto_restart=800 line, which will completely restart the
notebook server
every 800 seconds -- this prevents people accidentally (or on purpose) running
long-running calculations, which would slow down the machine for your use or
other people's use, and helps defend against memory leaks.
