In theory, if you are selling to customers in the EU you are supposed to collect VAT from your EU customers and make the appropriate VAT return to the VATMOSS authorities. Or else stop selling to EU customers.
In practice, if you're based outside of the EU then you can probably just ignore these regulations (many smaller US sellers seem to be taking this approach). It's hard to imagine the EU tax authorities chasing you down.
