Googling "belttop" just shows belts. To what are you referring? Are you suggesting wiring the glasses to some battery stored elsewhere? Sure you can do that, but I thought people these days hated wires (in spite of an objectively superior interface to wireless). But you certainly can't power streaming for it (for more than say an hour) with the battery you can actually store in glasses.

I've never even heard of an iVert.

> Plus people shell out $600 for the glasses

I want to sell these people a bridge. Pray tell me where I can find them because their money is absolutely begging to be taken for a pittance.
