Pretty good run down...
I find their emphasis on "free software" amusing.
Will this "free software" work with my checkout flow?
On my Shopping Cart page, will it display taxable shipping for those states that tax shipping, and vice versa?
If I integrate with PayPal Express or Google Checkout, will their "free software" record the tax correctly in my accounting backend?
If certain items in the shopping cart have different tax rates than others, will the "free software" display all of that correctly on my website?
With all the emphasis on "getting the correct percentage", I view that as the easy part. The costly part is all of the website and backend work that needs to happen.
