The only problem with the 2 RCCs idea is that you can't log in and control two RCCs at the same time. You can only form you persona on one device at a time, so you would need to reset the second RCC if you want to switch over and control that one...
That would be a bad idea. A device that you form your Persona on can not be part of a PAN. If the rigger formed his/her Persona on a RCC, any and all Drones slaved to it would no longer be slaved or receive any benefits from the RCC.
A rigger has to form their Persona on a Commlink (or Deck, but come on. What character has the cred for a "
spare" Deck?) and then "ride" the RCC networks.
In a very bad analogy, the RCC networks act almost like Grids at that point.
(On the Daisy-Chain topic)
I think the rules have been moving away from the idea of "everyone slave your devices to the decker" mentality.
That is only because the Wireless Bonuses were never really worth the vulnerability you created for yourself. And the more Matrix stuff Catalyst puts out, the worse the situation gets. (They keep making it more punishing to be Wireless On, without giving any real benefit.)
The only real exception is team communications. Self quoting here:
One of the first rules of combat is "don't allow your comms to be compromised." If one of your team's comms gets hacked, the rest of the gear being protected hardly matters at that point.
Feel free to click through to read the rest of the tip of the iceberg as to why this is a Stupendously Silly™ ruling, if you want.
It makes more sense to me that everyone controls their own stuff, and if you have a decker that serves as Overwatch on Matrix defense, they are simply keeping an eye on everyone else's PANs to check for extraneous MARKs. Honestly, that's a better defense in the current Matrix rules anyway, because if an enemy decker does get a MARK on somebody while everyone is slaved into one giant group that's a risk for everyone, but if everyone takes care of their own stuff then only one person is at risk at a time.
The big problem here is, it takes 1 Complex Action to inspect 1 team members PAN Master for extraneous MARKs. I mean, unless your GM allows the Decker to take a "snapshot" of each PAN Master and run a Matrix Perception - "Any of my teams PAN Masters that has extra MARKs."
Baring the GM being nice, then the Decker is just playing Wack-A-Mole. While they are looking at teammate A, teammate B gets hacked. When they move to look at teammate B, teammate A gets hacked. While they are dealing with teammate B, teammate A get's pwned.
At that point you are better off declaring "y'all are on your own," and / or not even running a Decker in the team.
