Here are the details of the talk I'd like to give at nodecamp:
Title: Streams, Pipes and Mega Pipes
One of the most exciting features in node.js are streams. This talk will explore the concept of Streams, the current APIs and how to build useful meta streams that ease the piping of data within an application. There will also be a look at the problems of buffering, back pressure and chaining multiple streams together (mega pipes).
