I would go for a first version limited to sales of online goods (music, photo, software, e-books, etc.).
Why? Because it would be easier to implement, hence faster to release and would be a base to which others could add new functionality. Something like QuickCart from opesolution.org but with a mySQL back-end, of course and PayPal processing. Plus two levels of tax and multiple currencies (so no need for multiple shipping options).
