If you've got 50 games to judge, anything that doesn't work immediately "out of the box" is bound to get scored badly. The trouble with network games, is that there isn't room for fancy client-server stuff, so you are almost bound to have to enter the IP address of the other player. This means you need two computers, unless your game also allows a port to be specified. Plus, unless the game is turn based, it's a bit difficult to play by yourself, when judging, and not great fun really.
So, you could enter one for the fun of it, but don't expect a great score
If it were otherwise, I'd be entering one. I was wondering how it would be judged if I entered several different 4k games that ran in the same battle space. Still it isn't going to happen, at least for 4k.
