okay, okay - I LIU (because this sort of thing interests me) and wagiman has a OI of one(1!); it's actually only to be found in wikipedia, which explains that it's "a near-extinct indigenous Australian language spoken by fewer than 10 people."
not the sort of thing that you'd find in an actual dictionary..
(yes, I checked OED and W3. nope.)
p.s. - it's nearly impossible to find a good obscure word with an OI of nil these days. blame the aforementioned amateur lexicologists (and me ; )
