[Christopher LILJENSTOLPE]

Ahh - I have to disagree here.  A VPN makes a virtual connection  
between two networks.  The state of those networks is entirely up to  
the people who run the networks.  I know of a LOT of cases where  
people use VPNs to tunnel puddles of networks over the public  
infrastructure to stitch a single AS together, for example.

As far as 1918 vs. globally unique address space, there are many  
"public" and "private" networks that use the later.  Anyone planning  
on using 1918 space for VoIP infrastructure that is going to connect  
to external entities is not really thinking things through (or  
believe that SBC's will make everything painless).  To quote Randy  
Bush...
