Not needed, if you can do minor hardware. The Arduino Uno can have it's firmware changed so it can talk to USB keyboards/mice. I have been doing research. Or, you can add a USB port, a few resistors and such, and then use an open source USB and Keyboard library and do it off a few I/O pins. I like your idea of how to get around the I/O pin limitation.

But, It looks like the Leonardo ($24.95 on Amazon) has 20 I/O lines, so that should do the trick.

Excellent!
