XML::Comma definitely looks extremely interesting, especially as a replacement for CGI::Application once you scale. I especially like the idea of reducing the need for the database, instead depending on the filesystem.

Unfortunately, I suspect that it would have issues in non-document-based applications, such as financial reporting systems. *ponders*
