So technically we are beta testing Nintendo's online service so they can turn around and charge us for it when they finally get it right?
Game link cables are suddenly looking much more appealing.

I would imagine most parents and for that matter most people don't like purchasing services with monthly fees.
$10 a month for Xbox Gold
$10 a month for PlayStation Plus
$3-$5 a month for Nintendo "Something Something Pay Us Money"
Prices really start adding up and thats if you only own 1 device.
Buy each kid a switch and of course your monthly bill doubles if you expect them to be able to play against each other.
Gamespy was free and match-making is really all Nintendo is doing.
It's only a matter if time till some one reverse engineers the service and starts their own private service for themself and friends.
I'm assuming the service only acts as a virtual router of sorts making sure each person has a connection to each other.
An i5 should easily be able to handle 4-8 people for this kind of task in a local environment.
