Technomancers [Outside the Box], If a Technomancer talks to electronics.. Options

[bardnoir]

First off - how do you guy handle a technomancer that keeps using certain equipment like a specific commlink or drones - do you make them roll each time for a new "access" and "command" roll or do you let the Technomancer have essential establish a line of communication with the device in question.

I was also thinking that if a Technomancer can talk to electronic devices, including the Street Samurai's cyberarm. And is basically walking around with a comlink in his head, where do you draw the line with what they can do? And how much can they focus on at the same time?
What do people think of the following NON matrix related activities.
Could it stand to reason that...
They can pick locks by taking control of the maglock and just telling it to open.
They would need a commlink to store ARE programs but they can interact with them without the need for a datajack.
They can watch simsense and play games on someone ELSEs commlink just by hacking into it.
They can jump into a comlink and get a list of phone numbers without leaving a trace that it was hacked (only another Technomancer would see the traces).
They could hack someone's commlink, tell it to display an ordered image on screen and make their own image on screen thus "Max Headroom"ing the person on the other side.
Send a command to a printer to just start printing whatever he's thinking (or visualizing).
They can command drone without the use of a rig (just send the order to the drone and let it go to work).
Hack a holoprojector to make a 3d image of himself (thus being able to interact with others and not having to actually BE on location).

So couldn't they also use smartgun? They just hack into the gun and call up the AR signal and use it in a similar fashion to everything else they do?
