Indeed, a web page that does not control another application
programmatically  is an interesting comparison.

But I imagine that the new world's operating system, HTML5,
is perfect for obfuscation again: it is about at which end you keep
status information and then, about how the ends of a web program
use it later. For example, you can store status in both
browser local storage and in server side storage. Then,
distribute the whole program's status dependent control
both across web pages and server side programs:
Write source text, e.g. JavaScript functions, that has effects
at the server side, knowing that a later  JavaScript function
will then work as intended. Written in such a way, studying the source
of the client side will not reveal anything about the logic of why
the first function controls the second, indirectly.
And neither will studying the server side source reveal
how the web end logic depends on the interaction.
Reminiscent of the PHP case, isn't it?

In fact, according to Douglas Crockford speaking on stage
(URL was posted here recently), vendors are trying to push 
for a change to JavaScript that would make it a better object
code language. They are selling tools that reuse their existing 
language offerings and will produce Javascript output.
