S6E9 WHO IS THE ISLAND BOOKING AGENT?

MIB has cursed to Jacob about his constantly bringing people to the island. MIB has found no redeeming qualities in those brought to the island because in the end they all fall prey to corruption.

But the question remains: is Jacob the only one who can bring people to the island?

This was strongly inferred this season: that it is Jacob who brings people, like the Black Rock, to the island. A maneuver which by the way destroyed the Tawaret statue where Jacob was presumably calling home. Why would someone try to do that? Unless, of course, Jacob brought the ship into the sphere of the island, but then MIB caused it to crash toward shore, in an attempt to kill Jacob while he was in the statue. This could explain why Jacob was really ticked off when Richard came to his beach (that, and having a knife with murderous intent). Jacob's tapestries must have gotten soaked in that storm!

Is MIB-Smokey trapped within the "snow globe" effect of the Island? Can he only influence physical matter within that island zone? Or, if MIB can teleport off-island to influence or bring people to the island just as Jacob can, that would make things much more complicated or devious.

For example, it appears that Jacob brought the 815ers to the island, the Ajira plane, Richard, and the Others. We assume that Jacob also brought in Dharma, Ben and the Others, too.

But if only Jacob can bring people to the island, then does that mean Widmore's arrival was with the consent of Jacob? It seems that Widmore's arrival has evil intentions aligned more with the current Team MIB concept.
