I'm primarily looking for alternatives to MVC frameworks for web
development, particularly SAAS. I've looked around, and some
whitepapers suggest that event-based frameworks often perform better
than MVC. Since I'm looking at SAAS, having a "view" is pretty
pointless since I'll either be using Thrift, returning simple HTTP
headers, or returning some sort of JSON/YAML/XML content (possibly
based on accept headers).
