I think we need such legislation, with the caveat that there needs to be an easy way to compute the amount of the tax. (Figuring out what sales tax rate would apply at the purchaser's exact location is hard because of county and city taxes. In some cases the 5-digit ZIP code is not even sufficient.) A single tax rate for all such sales is probably too simple, as it would put online retailers at a disadvantage when shipping to a state with no sales tax. A single tax rate for each state might work. At the other extreme, it could probably be done based on the 5-digit ZIP code, but I don't think it would work to go any finer than that. Even at that level, we'd need an online service to do the lookup.
