This will not work on Broadway. I am not talking about it from a logistical standpoint (though there were a couple of goo points regarding that that could work in theory.) I am talking about from the me working as an usher standpoint.
First off, this will be another task that will get assigned to the ushers should these be used. If they were to be used in Broadway theatres, and that wasn't the case, I'd eat my own shoe. Secondly, the major difference between Broadway theatres and major concert venues as far as something like this is concerned is staffing. Major concert venues have a much larger usher/security staff than any theatre on Broadway meaning that there are more people to dole out the pouches/help out if need be etc.
Take the super hit show Hamilton for example. I've worked there a few times, when I do, I've been in the Mezz. And, there's a two person rotation. One is on break, other is stationed inside being a physical presence in case someone has an issue/ watching for phone usage. I don't think that two people would be enough to deal with any issues arising from these pouches being used. Enough to control things at intermission and walking out? Sure, but not for something like this. Specially if there are many people who aren't sure how to use them/find them confusing, which I can assure you will be the case.
ETA: Also, I think that something like these pouches would be up to the production not the theatre owners. The article was talking about how in these examples of the pouches being used, it was the artists who wanted them to be used rather than the venue itself. Almost all of what the ushers do is at the instruction of the production. Late seating holds, what of the set can be photographed etc.
