Testing interaction across multiple simultaneous browsers?

Question

I'm trying to figure out if there is a good way to test an application where a considerable amount of the complexity is in ensuring that changes made in one browser to a document are correctly pushed to the other people viewing that document, without them having to refresh the page.

Does anybody know of a reasonable way of automating a test for this? I'm using rspec with capybara currently.
