Thank you for the reply.
Understand the point on Skinlink, Auralink and Resonance Wires. In addition Resonance Wires is sustained, meaning -2 dice on everything or taking up a valuable slot of focussed concentration quality.
On 3. and the Puppeteer...
A) Assume a device, which is not part of a host or PAN, lets say a trideo projector waiting for signal. I could directly use Puppeteer on that, as I can simply connect via AR matrix?
B) Assume a device, which is part of a public host, which can be entered from the matrix with guest access level. I could use a minor action to enter that host in AR and then use Puppeteer on the device?
C) Assume a device, which is part of a PAN, which does not allow any actions with guest access level. Can I still use a minor action to enter than PAN in AR and then use Puppeteer on the device?
D) Assume a device, which is part of a nested host, where the host of the device cannot be reached directly from the matrix. In that case, I first have to enter the public host, then work my way into the nested host (via Brute Force or Probe/Backdoor) until I have arrived in that host, then use Puppeteer. Benefit of Puppeteer could be that I have used Brute Force to achieve guest access level and want to avoid doing that again to get to admin, so I use Puppeteer to control some device that needs admin access.
If ABCD are true, then the only situation where Skinlink (or similar) is better for device control than Puppeteer is a nested host.
Usage example: Rigger approaches a red traffic light. Technomancer want to switch that to green (and switch crossing directions to red, to avoid accidents). The traffic light is part of the gridguide guide host. But that is not nested. So Technomancer sees the gridguide host in AR, uses a minor action to enter the gridguide host as guest, then uses Puppeteer on the traffic light and leaves host again?
