Alot of software is written for single instance data, thats the way IT has evolved, so whilst clusters are in their infancy, the market perhaps hasnt evolved enough to recognise their benefits, and the laws would need to be upgraded to be consistent across borders. But you do already see instances like this, like window machines distributing updates to other local window machines. A great way for MS to offload its bandwidth costs onto users, whilst saving itself a packet or two. So maybe the market has recognised the virtues of distributed systems, but they are not how you envisage them to be?
