tee nine

Some notes on T9. perl-fu used to prove interaction design-fu:

The patented iTap/T9 system uses a dictionary (does it also use a general language model?) to decode the string back into english characters. In the event of any ambiguity, the user uses scroll commands (embodied on one or more other keys) to select the desired word from a list offered by the machine.

I was curious to find out how good this code is for English. I could see it being bad in two possible ways.

1. Assuming that the user is purely typing words from a dictionary, how often will the user have to use the disambiguator, (Example: KISS = LIPS = 5477, and PUFFS = QUEER = 78337!)
