In short: forget about it. If you're allowing users SSH access for X2Go, they WILL be able to copy data. You can make it a little harder for them if you think you have to, but as long as they are in control of the client hardware, they will always be able to do so.
I have no complete answer to it, but if you use keys instead of user/pass then you will be able to restrict ssh in ~/.ssh/authorized_keys
from="1.2.3.4,2.3.4.5,9.8.7.6",no-port-forwarding,command="/path/to/script",no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa <key>
(all in 1 line)
This is an example of what I use here, I think there must be many other options available.
see "man authorized_keys"
