In many ways, a pcAnywhere session, or Citrix, or RDP, made to a managed server 
rather than any old desktop on your side of the firewall, can be more secure 
than a more open VPN or SSH tunnel.

One question that hasn't been asked (but I've not been following that closely) 
is why pcAnywhere was needed? SSH may not provide access to the licensed and 
restricted software installed on the desktop the user wants to reach.
