Wow, that's a really shit way to do it. Bare minimum, it's going to take a couple of seconds to re-negotiate the link. Depending on the connected devices and how they're configured, it also might sit there and try to re-acquire an IP address rather than just assuming it should continue using the one it had (some devices do this when they lose the ethernet link for long enough). You could end up breaking connectivity long enough to dump yourself from the game.

It seems to me that a much better solution would be software on an in-the middle device (a PC, or a router with modified firmware) that just delays sending packets through. Probably pretty difficult for most people to implement, though, unless someone makes an actual product out of it.

There was a time when a lot of modems had a "hold" button on them or something like that, which would actually interrupt the connection somehow. I'm not clear on what the purpose of that was supposed to be, but in practice it was mostly used to win games of Halo 2.
