Forgive me if I seemed flippant about the Masters-as-Slaves thing. I personally would have no problem with allowing it, I just think that you canīt really give "technical explanation" for man-made software protocolls: Someone decided that a device cannot be a Master or Slave at the same time, and now itīs part of the Matrix protocols.
Well, you wondered why everyone wanted to daisy chain PANs. A reason is that it is a fundamental part of our modern technology. The idea that the future went
backwards on that is kind of hard to swallow.*
It doesn't make sense, so it won't "stick" in players minds.
To make matters worse, it isn't even made for a good reason. It isn't like Wireless Bonuses are going to make or break
anything. Even from the start, they felt like an afterthought. The cherry on a sunday. Sure, they may be the best part to some people, but nothing about the game would really change if they were suddenly removed.
*It is one of the reasons 4th Edition brought Wireless into Shadowrun. At the end of 3rd, it was getting harder to swallow that there was no wi-fi in the future.
When you (generic) come out of nowhere to say "You can't do in the future what you can do now," without there being an obvious reason for it... It just doesn't make sense. Right now, it comes across like it was arbitrarily decided to punish technology based characters - as if they are the ones that are the most game breaking.
In a tangentially related subject, it is a similar situation to the whole "movement on the Matrix" discussion we are having. Even though it is not technically correct, we (collectively) think about "going out on the web," "going to site ABC," not bringing those things to us. Not to mention the visuals for any VR computer experience always have the avatar moving to their destination.
There wasn't any defining point, that I could find, in the rules to make it clear how the Matrix worked in that regard. If the Matrix changes how players imagine the way the technology works, it needs to be made clear.
Then again, like with the chaining PANs, it still might not sink in.
