[X2Go-User] Possible to use server SSH key like FreeNX?

[Jasmine Lognnes]

Dear readers,

In FreeNX it is possble to change the default SSH key, so in addition
to have a valid username+passphrase to the host, the user also needs a
SSH key. The SSH key is the same for all users.

Is this also possible in x2go?

Kindest regards,
Jasmine =)
