Streaming support?

[Kikobeats]

I'm in love with the library, but what about something important in node as streaming?

You can find a good case of use in request streaming

maybe you aren't interested in because is more difficult tu add support for this feature in all the platform compatibles with the library, but I have to ask! :-)

You can use the underlying request library to do streaming if you want, I am open to a pull request either on this branch or the 1.0 version to add streaming.
