Okay..   Here is my question, and it seems to
relate to a question someone asked about vi and shell escapes.

I need a simple, vi-like screen editor, possibly vi itself, that
has the following security precautions:

no shell escapes
no :r or :w or :e of other files..  unless I can limit the files
to a certain path

I do not have su capabilities.

a .exrc file would be okay, because it could be made so that it can't
be removed.

The environment this is going to be run in, and the reason I need
it setup as such is this:

the users will telnet to a machine at a port and be given a shell

from this shell they can uses limited versions of certain commands,
such as cd, rm, tar, compress, etc..   where the args to the commands
are checked to make sure they stay within a certain path...

I want them to be able to use a screen editor, preferably vi, but they
can't execute shell commands or be able to read or write files, because
then they could do things like write over the files of the person who
is running the shell process.

I am willing to use a simple editor that can have its source changed,
any suggestions ther?

Or is there a way to do it in vi, perhaps using .exrc?  And is there
a way to specify the .exrc file when running vi?

Mail would be appreciated, ljung@cae.wisc.edu

Thanks,
