That is the online content that they generate and make use of, yes. But it still makes use of the Nintendo Wifi Connection service. Online Compatible DS games are hardcoded to go to a specific Web Address for communication. There is no changing Web Address that except through ROM hacking. The workaround for that was to use a DNS server that makes that Web Address point to a completely different IP Address. This can be used for the Pokemon games, but it could be extended if somebody had the time.

The problem then would be to figure out how each game communicates with their online functionality. It was done with Pokemon because it's Pokemon. It could also be done for other games, if enough time were put into it.
For the sake of example, by making the fictional http://www.nintendo.com/wifiservice/metroidprimehunters point to a different IP address, if someone had the knowhow it would be possible to make a spoof Nintendo Wifi Connection Service that allowed Online gameplay.
http://save-nintendo-wifi.com/ is a project seeking recruitment for figuring out the connection methods for other games.
