dedicated network inside of a machine room that can have
In your design recall that a VPN extends your network out to boxes
that you have little control over in numerous locations and viruses or
other security breach way out there is now 'inside'. i.e. It is
tempting to think
that VPN provides access to a network where you have physical control of

You clearly will be under pressure to get it 'live' which is OK
