Yes, except it is done via Switched Ethernet and VLANs. The idea behind virtual peering. Your gear is in Amsterdam and someone gives you VLANs to LINX.

A virtual Point Of Presence means that you provide services at a
location via someone else's facilities.
The classic example was extending a PRI for dialup modems inside a
particular local calling area via a point-to-point T1 back to your
modem bank somewhere else that would have been a long distance call
for those customers. If you put a modem bank in their local calling
area, it's a POP. If you extend the circuit from their local calling
area back to your modem bank elsewhere, it's a virtual POP.
Modern examples of virtual POPs are much fancier but it's the same basic idea.

It can be. Depends on what service you're extending from the "virtual" location.
> 2. Do such vPOP have guaranteed latency/bandwidth?
Depends on what you're extending and how.
> 3. Is that really useful?
It can be. It can let you dip your toes in a market without a large
up-front investment in equipment and backhaul.
