I looked at run-mode specific JS, and decided: Just Don't Do It!

I adopted a JS library (YUI), and now send all required JS down to the
client in the very first response. Thereafter I use Ajax.

The consequences are that the first page load seems a bit slow for the
user (maybe 300Kb), but that's not really all that much these days.

The big gain of course is that /all/ subsequent responses are lightning
fast, since only data is sent.

The other factor is that any JS feature can be used on any 'page', since
the code has already been sent to the client. And if it hasn't, then the
first page has to be re-done. But that's a tiny issue, and hence the
ongoing maintenance problem of matching JS file to page is thereby
eliminated.
