Not now. Capybara is designed to work with a Rack application. View specs are built on Rails' ActionView::TestCase, which is designed to make an isolated call into the rendering framework, and get back a String. They don't know anything about requests or sessions, so the Capybara matchers don't work.
I've talked to Jonas about extracting the matchers so they can work with arbitrary Strings. He's interested in the idea, but it won't likely happen for a while due to other priorities. I've added an issue , which you are welcome to comment on and follow.

Why would Webrat be any less clean in this case? The matchers are pretty much the same, and that's all you need. Are you using Capybara in controller specs? If not, I'd recommend using Webrat with RSpec and Capybara with Cucumber.
