Configuring your log levels to go to different transports in winston

By default winston uses the following levels:

var levels = {
  silly: 0, 
  verbose: 1, 
  info: 2, 
 warn: 3,

Implications for EventEmitter2 and .pipe() APIs

I have been working on refactoring [node-cloudfiles][0] to use @mikeal's [request][1] library for HTTPS uploads now that they are more stable. The current [pull-request][2] makes use of the continue event which it seems is not handled by the default .pipe() handler (for good reason). The work around potentially supporting this in [request][1] has made me revisit the need for EventEmitter2 with some new arguments that I find more compelling that those which were laid out before, that is: Selective Piping.

Selective Piping

Suppose that you wish to pipe arbitrary events from one stream to another, but only those which are relevant to your concerns. For example, if you were piping an http.ClientReqest stream to an http.ClientResponse stream you may wish to only pipe those events relevant to the http module (i.e. ignore those events from net.Stream).

If we were to use EventEmitter2, we could namespace these events u
