Interesting JS proxy that catches all client-side exceptions and mails them.

From their blog:

When a request reaches proxy.proxino.com, we lookup your existing code, parse it into AST form, and walk down the tree inserting special try/catch blocks within each function definition, as well as around the file itself. We then serve this instrumented file to your users, and handle every exception that occurs.
