"Protocol Agnostic" "Protocol Agnostic" is PR-speak for all protocols. Nothing is off the table.
Until their network can sustain the traffic they purport to sell, I predict their "network management" will be to throttle all traffic. Whether they discriminate against the bandwidth hogs or against all subscribers at random remains to be seen.
The nature of their distribution method has them between a rock and a hard place no matter what they do.
They've already got "up to" language in their service description. They should throttle the heavy users back to let the lightweight's traffic get through.
But the key is to let subscribers know what they're doing. Transparency is good.
