Cloud computing enables us. Amazon's EC2 allows anyone in the world to have instant access to incredibly powerful high-end servers that would usually cost tens of thousands of dollars for pennies on the dollar. ##Life is good.
Of course, people use this technology for both good and bad. In fact, a few days ago, someone wrote a tutorial for Cracking PGP with an Amazon EC2 instance & EDPR. Again, life is good.
Remember: if you create an successful open door web service, all people, good and bad, will come.
