I have found wisteria to be persistent rather than invasive. I planted it in a poor spot, moved it, and am still randomly pulling up little attempts to recolonize the old spot. It hasn't been a problem. I saw a really lovely wisteria a few years back that had been kept pruned to very few main trunks rather than a spider web of coils.
When my younger son was at that weird age of about 9, he thought planting a wisteria around a person would be the perfect form of torture - death by slow squeeze. I pointed out it would likely take years, but he just liked the general idea I think.
