Update: Beta 2 Released! See the Gaebar Beta 2 announcement.
The launch of services like Amazon's EC2, S3, SimpleDB and Google's Google App Engine herald the birth of the Commodity Web, wherein web infrastructure is infinitely available and metered just like electricity, water, and gas. For the most part, we don't think about the limits or availability of commodities (as the impending ecological nightmare we've woven for ourselves would attest to, if nothing else.) But when we do try those limits, or when the systems of delivery break down (as in blackouts, for example), the extent of our reliance on these utilities becomes painfully clear.
