However, this is far from being elegant and is not scalable at all, as the call would be contextless to the spec that needs it. 

How about putting it in a step/step definition before the call gets made?

Now, I know this is not something that would prevent me from using the :rack driver for Capybara, but it made me think of the following problem: What to do when you have a JS/Ajax-oriented page that makes web service calls and you need to write an integration/acceptance test for it?

This essentially prevents any mocking/stubbing/faking of requests. I wouldn't want a bunch of acceptance tests that actually make requests to web services, certainly a testing no-no.
