How to set up a command-based communication using I2C

I know ! and it is really bad. I want domi1 to write normal code that he needs instead of copying code that he does not need.

I think that this makes more sense (not that I'm totally happy with it):

void receiveEvent(int nBytes)
{
  int i;

  if (nBytes > 2)          // at least 2
  {
    command = Wire.read();
    commandLength = Wire.read();
    if( commandLength < BUFFER_SIZE)    // reserve one for zero-terminator
    {
      for (i=0; i<commandLength; i++)   
      {
        commandBuffer[i] = Wire.read();
      }
      commandBuffer[i] = '\0';
      printRequest = 1;
    }
  }
}

[EDIT] Changed the code, added BUFFER_SIZE.
