For operators already offering FR/ATM services, it was a replacement, using the same principles of traffic

Indeed. But the difference with Frame Relay and ATM was that telco's never called it a (V)PN. At worst, it was a 
leased line.

Private line was a common term for leased lines. Leased lines were not encrypted by the operator, AFAIK. This 
terminology morphed to virtual private line, Ethernet Private Line, virtual private LAN service (VPLS), etc.

"In telecommunication, a private line is typically a telephone company service that uses a dedicated, usually 
unswitched point-to-point circuit, but it may involve private switchingarrangements, or predefined transmission 
physical or virtual paths.”

VPN is a terminology consistent with past practices. It is P in all the ways discussed on this thread, and historically 
consistent (at least from a marketing perspective). Whether it is P enough is a reasonable discussion, everyone in 
I(C)T is going to be facing a wave of voter concern about privacy, IMO.

Or someone else who might "capture" the operator, and thus, be able to intercept it.

Good point.

If gubbermints mandate that l2vpn's and l3vpn's be encrypted, the cloud bags will simply take over (not that they 
haven't, already).

Torn between two lovers: Growing voter concern about privacy & longheld, and arguably increasing, desire to intercept 
criminal / terrorist communication. I’d actually be curious if any operators have received public sector pushback when 
they tried to implement encryption.
