There are several good ways to get more IO

1. Adding a cheap brain dead PIC12C5x,  PIC54 or 505 and talking with it
through some serial protocol - rs232 or I2C

2.  Adding a simple shift register such as a 74LS595.  I'm using this trick
to drive an LCD.

3.  Ingenious combining of inputs and outputs.  This will usually cause
trouble in the long run.
