Is it safer to use a chroot jails, a jail shell or a combination?

"A friend of mine has a xandros-based Acer netbook, and has been looking to get some remote administration and help from me while she is travelling around the world.
I've set up an account on her netbook for me to ssh into, and set up a script to reverse-ssh-tunnel from her netbook to my server - this lets me get around the problems with firewalls etc at various hostels and hotels. Once she has ssh'ed into my server, I can then ssh along to her netbook."

I am a fan of a good defence in depth strategy when it comes to securing a computer system, so I would recommend that you use a low privilege account in a chrooted filesystem, and even then it is no guarantee, just look at the iPhone, it does both of these things and it still doesn't help.
