In fact, the term VPN itself is a buzzword.

Nowadays, VPN means nothing else than an IPsec tunnel throughout the 
Internet which makes a node from outside a network behave and feel like 
a node inside a network.

Some years ago. I found the term VPN used for a number of FR connections 
offered by some telco in oder to establish a company network connecting 
different locations.

So, the term VPN is somewhat "polymorphic" :-)
