serial input from chip

Is it possible to add another serial RX port on arduino? This will make it easier to gather serial input from sensors (like RFID and touch sensors) and then to send this serial data over the other serial port to the computer.

Software serial (serial on pins besides 0 and 1)

yes, but i'm wondering if this could be implemented as a library or a predefined function:
i noticed that wiring board has Serial and Serial1 for this purpose
