The HOWTO is being actively worked on and Essex was only recently released. As a result I'm not confident that you will succeed in easily implementing the HOWTO with the variations you suggest. It will most probably require a few upstream patches ( a number of patches were committed upstream because they were necessary to succeed ).

Right ! This is a bug. I thought about it but forgot to fix it. It's done.

The "Install the VNC console" has been removed, it's confusing. It is enough to follow the instructions.

Thank you for the feedback ;-)
