Ok, I follow you on the wired/wireless distinction inside the SCIRE, Crimson.
Regarding Mirage, one thing else that could've given it an advantage in creating its otaku would be its experiences with the Echo Mirage team. Its core program was beneficial psychological and physiological feedback to support the team and it would've had its own extensive log files of the the time the team was active, which was a long time. Its core program, more or less benevolent nature, and of course access to the full resources of the matrix... together I think the reasoning's as good as any for its success *shrug*.
