I'm not sure which side of this I see it falling on. I have a feeling that the ruling will be in favor of the State to enforce the collection of sales tax by the selling party. The $100k threshold seems reasonable as that would still allow hobbyists and even full-time-but-still-small businesses to not be burdened. I'm pretty sure the Quickbooks of the world already allow for this. I would think that most eCommerce sites can add the tax collection pretty easily also.
