The end of reposiphilia?

One sure sign that Web 2.0 is a genuinely new epoch in the tech industry: the haymaker punch it threw at a repository-centric view of application architectures, effectively knocking it out of the ring. For those who aren't familiar with what I'm talking about, I'll give a little bit of history for the young 'uns out there.
