I'd say it is much, much better than trying to re-invent
a different secure connection protocol.

The real login does not have to run over ssh or use encryption.
That is optional and a waste of CPU if not needed.

It's not that bad compared to a lot of other ways they might
have tried to ensure that the real user password exchange is
encrypted.  The nomachine server always uses the same key for
for the nx user and trusts the shell program to not permit
anything but the next stage login to happen.  That eliminates
the key-setup issue that you have with the freenx variation
which builds new keys during the install on each server.
