(Tangentially connected to Youneko's query above)
1)
Rigger 5.0, pg 30 states "All of the following actions are Matrix action. Yes, you can use them if you're not a rigger." Yet, the language of many of those electronic warfare matrix actions seem to heavily imply that they can only be used by an RCC.
For example, Target Device says:
"Pick a wireless enabled device you've spotted on the Matrix. You can target that device and feed targeting data to any pilot program or person with a Sensor rating or smartlink that is slaved to your RCC."
- So can you, in fact, use these matrix actions with a deck or a comm?
If not, then why not? What would enable an RCC to find / calculate / share targeting data it acquired by electronic warfare vs a Matrix icon, that a deck or comm would lack?
I suspect the true answer to the above is that comms and decks can in fact target anything that has an icon, and that this is partially due to the way that the Matrix overlays with the physical world. This brings me to my second query of the day:

Considering how AR Fashion is a thing that exists, combined with how pg 221 of Core's fluff states "... and the people walking down the street are occasionally highlighted by glowing auras--nice blue ones representing your friends, glaring red ones telling you that someone you know and should be avoiding is coming close," it seems pretty clear to me that you should be able to highlight a device's icon with an ARO, then anyone who has eyes on the physical world counterpart should be able to see that ARO highlighting the device itself as it moves around in the meat.
(Of course, this is very different from the Trace User action because it doesn't actually give you any kind of gps data. Instead, you (or someone you're sharing AROs with) have to physically be within AR range of the device in order to see it. This is largely a quick and easy way to share data with your team about which person running around in front of you needs to be in your crosshairs, etc.)
