C++ custom stream

How do I implement my own custom stream in C++?

Why?

I want to send data from one micro-controller to another using a wired connection and I think a custom stream is the most intuitive way.

Example:

#include "myStream.h"

int main()
{
  myStream << "Hello world!";
  return 0;
}

EDIT:

Solution:

class Stream
{
private:
  // members
public:
  Stream() {}
  friend Stream& operator<<(Stream& stream, const Whatever& other);
};

Stream& operator<<(Stream& stream, const Whatever& other)
{
  // do something
  return stream;
}

If you look at how streams work, it's just a case of overloading operator<< for both your stream object, and the various things you want to send to it. There's nothing special about <<, it just reads nicely, but you could use + or whatever else you want.
