Marcus, Kiirnodel's last post illuminated something for me that maybe explains why you have trouble accepting what everyone is saying:
Remember, unless something is being done to specifically augment the matrix, it isn't a 100% 1-for-1 representation of the world around you.
The discussion spiralled out from my saying that someone could attend a meet with Tanaka-san in AR, and (my understanding of) the foundation of your complaint with my claim has been basically "then why don't we see descriptions of AR personas flying around in the corpus of area descriptions".
Let's back things all the way up to my claim in the SRM thread that you can attend the meet with Tanaka-san virtually, in AR.
All things being "normal", ok you're right in that visiting a remote host in the matrix doesn't work as a direct matrix analogue for Astral Projection. If a matrix user in Seattle wants to access the host for a Neo-Tokyo business, his persona doesn't appear to people in Neo-Tokyo... the host he's accessing is simply perceptible to him across the matrix in Seattle.
But that's not what I was referring to. I was referring to the examples of people's matrix avatars (both AR and VR) interacting with people in contexts such as those described for Dante's Inferno and the Neo-Tokyo business downtown... the key thing that makes it work is both the "ghost" and the perceiver must be logged into that same host that provides the functionality for the ghost to see a 1 for 1 digital rendering of the physical world and for people physically present to see the persona interacting with that rendering.
So yes, technically, when I said "you can just AR ghost to the meet with Tanaka-san" that was including an unstated but I thought understood provision that "so long as you, Tanaka-san, and the rest of the team all are logged in to a host that permits such an interaction". That's not a reasonable assumption for meets in places like a burned out warehouse, but it is (imo) fairly so in the kinds of places you meet in the Neo-Tokyo SRM campaign.
But the key thing is, since you can't see across a Host's matrix event horizon (those inside a host can't see icons outside the host, and those outside a host can't see icons inside the host) THAT's why you don't see descriptions of matrix personas (AR or otherwise) zooming around the AR landscape in the corpus of canon.
