Notice that the GA code bootstraps from the user's server.

You'll probably want something similar, in that you provide a bootstrap
function that loads from your customer's site. That function then loads
your GWT code. If the load fails, it fails on your customer's site, not
your site. You can take action since your customer's page has loaded,
but with an exception (it hasn't loaded your GWT code).

There may be other, unexplored complications to this solution.
