If that were true, you'd be able to conceal your own access ID merely by encrypting your commlink.  Also, for spoofing, it's not the target node's ID that you need, but rather the ID of a user with the right authorization.  Further, you send spoof commands from your own device, but you're making it LOOK like it's coming from somewhere else.

The troll can really get nasty if she takes Krav Maga and gets the free reload perk of it. Then she could shoot twice. And a tanky troll shooting twice with a bow is...painful. And it wouldn't force a 'ware/power choice and isn't stupid expensive karma wise either.

IP's are nice. 20 Dice pools are nice. But they aren't required if that's not the style of the game.
