I write and sell software so at the moment I have had to block all sales to the EU (thankfully most of my sales are outside the EU) however my latest concept would be to supply a different version of the software and licence that will only work with physically supplied media like a memory stick or CDROM and not with the online version of the software.

That way the software would be no longer be deemed as elctronically delivered and therefore not fall under the EU VAT rules.
