Are multiple VAT/Tax values possible in Marketpress

I'm thinking of installing Marketpress, but I need to know whether this functionality is supported.
I would like to display all products without VAT/tax added (this to be added in the checkout). However, the VAT on some of our products is 20%, on others it is 0%. Is it possible to set different VAT rates for different products?
Working out the VAT on shipping gets even more complicated, but I'll leave that for now.
