Basically, I have a custom wrapper around jQuery's ajax request
functionality that defaults to common config values for my app (always
GET for instance) and so I've just hard coded that wrapper to always
check for app_namespace.app_url so that I don't have to enter it into
more than one location.

I try to keep all my javascript out into a external JS files vs in my
mako code. This way I get better editor support for things since it's
just JS, I can minimize it all safely, and I don't have any JS/Mako
combo issues.

What config values do you need from your pylons app to JS? I've not
run into any other than the url I've needed to worry about. I guess if
I had additional ones I'd just treat them the same as the app_url.
