What does it actually take to slave a device?
In terms of MARKs/ownership and action type.
Do you need to be the owner? Have 3 MARKs on the item? Does it take a complex action to slave a device? Less?
PANS and WANS section, pg 233 tells us we CAN slave devices to comlinks, or cyberdecks to provide them with improved protections, but I can't seem to locate any info on whether you have to be the "owner" of said devices, or even have any specific number of MARKs on them to perform slaving.
The book does indicate that the Master is not necessarily the Owner of the device, so maybe it just requires Owner access to perform the slave action; but then, do you need like 3 marks on the hackers cybedreck to get it to accept the slave, or maybe your just 'offering' the slaving and the cyberdeck owner has to accept with some type of action...
Since the team hacker may want the rest of their team to slave their vulnerable equipment to his high-end cyberdeck for protection, its kind of important to know if they can do it without making the hacker their device's owner too.
On the flip side, a rogue hacker in a host might want to slave a device inside (like a gun turret) to his own cyberdeck; if slaving does NOT require ownership, it seems like the hacker might be able to accomplish that, taking an asset away from the host, at least short term.
