This question seems not related to concurrent stuff but rather pure regulatory but I suppose that will depend on the definition that the FCC intended behind GO concurrency. Is the definition of concurrency GO thing supposed to *restrict* the number of interfaces a device can create (STA, GO), or simply define permissive rules which would have otherwise been blocked?
