What are you talking about? The characters know exactly what's happening, and this offers a supplement to the current system and a better explanation as to why it's on RPG in the first place. Changing from a network system in the first place was less logical a jump.
I like the idea of having a marker. It actually rather makes sense, since it's coming from devices. If we consider the idea that what we see is from cameras recording everything, then they'll record the speech from the devices, as well, and we can put that in markers to show that it's coming from the devices.
