We've decided to try an experiment on find.mobi: server-side T9: if you type in a purely numeric query we will try to see if it maps to any common words in the English language, and offer you a link to the search. Thus searching for 46835 will ask you if you meant "hotel" and "7464 8663 " will suggest "ring tone".
For the time being we list only the most likely words for a given number sequence because the permutations quickly get complicated to display with multi-word queries (multi-number queries actually).
Is this a useful feature? We're not sure yet, but it was worth trying. Find.mobi has a nice plug-in API that lets us try these little experiments without touching core code. If people use it we might try an AJAXy version for Webkit/Opera browsers.
