Okey dokey - got some clarification on the Matrix stuff (and a further question)
First off, want to issue an apology, because apparently I was wrong about the security devices slaved to a host.
The only icons that can be inside a host are IC icons, persona icons, Mark icons, living persona icons, sprite icons, agent icons - devices are not inside the host, they are outside. However, anyone in the host can still see them, since they are considered directly connected to the devices.
Here is a summary from Xenon on the Shadowrun forums:
"So, it look like a device icon will never be inside a host. It will always be out on the grid (but if slaved to a host - part of a WAN - it will use the host ratings when defending). You also have a direct connection to the device from within the host (don't have to fight the host ratings... but you first have to hack your way inside the host anyway).
That mean if you see a physical device you can also see it's matrix icon with augmented reality (unless running silent mode) and you can always interact with it even if it is slaved to a host (belong to a WAN). But if it is it might use host ratings when defending itself.
So the advantage of attacking a device directly from the grid is:
- That there will be no IC.
The disadvantages are
- The device will use host ratings while defending
- Security decker might still come after you even though you are out on the grid
- Devices defending themselves out on the grid will generate overwatch score for you.
- demiGODs can converge on you since you are out on the grid.
- Suffer noise penalties
- Suffer working across grids penalty
The advantages of attacking by the direct connection from within a host are:
- Device will not use the host ratings while defending.
- demiGODS can not converge on you (but host instantly get 3 marks on you)
- Don't suffer noise penalties while inside a host
- Don't suffer working across grid penalties while inside a host
The disadvantage being that:
- A host can, and will, run IC
- You first have to hack the host"
The upshot is that Slacker was correct (mea culpa again) the devices that are slaved to the host are still visible outside the host in AR or VR, and if they are running silently are a viable target that Natasha could pick up with her scan.
To answer your questions:
1) I am running on the local grid - which is Emerald City since we are in Seattle - and Emerald City is run by NeoNet. Can't speak for the others on the team.
2) Silk's backup and the NPC decker being in the host mean that although they can interact with the devices slaved to the Host, they cant interact with the icons outside the host (so for instance, the NPC can't Data Spike my commlink, because he is inside the host, and I'm not). He could, however, lock doors or move the elevator or Data Spike cameras that are devices slaved to the host. The fact that they are outside the host is trumped by the fact that they are slaved to it.
3) I am not sure (am asking for clarification) that the -2 for being on a different grid applies. If it did, you would have to specify which grid you were searching, and since there are at least 12 grids the person could be on (public, local, and the big 10 global grids) that would mean a lot of guesswork. Alternatively, if it applied and you could just say "Looking for silent icons within 100 meters", then you would have to roll twice, once with the -2 penalty for all icons NOT on the same grid as you, and once without the penalty for those on the same grid as you. Now, once you do find the icon, if you want to DO anything to it, (like Hack on the Fly, Data Spike, whatever), if you are on a different grid then you do take the -2 penalty. Will post what the answer is when I find it.
Now that that is all out of the way (which was helpful to me, and hopefully others), I have bad news (for me anyway). Apparently I somehow had a brain fart and was looking at Matrix Perception as a regular Perception check - ie Perception + Intuition - as opposed to what it
actually is, which is Computer+Intuition. Since I don't have a Computer skill (although it is one I am allowed to default), I roll my Intuition -1. Since I take a further -2 penalty for running silent, that means I roll a whopping 1 die. I said I was taking the action, so
here it is, and of course I critically glitch - serves me right, actually, for being wrong on the whole devices and host thing (not to mention screwing up the skill

)
4) You are correct, that if you don't have a device slaved to a deck or a host, they only have a Logic rating, and so they are much easier to spot.
So let me know how you want the glitch to affect Natasha, and I'll be happy to write the IC post (or you can do it - however you feel more comfortable).
