Yesterday my boss called our design person on the phone and asked her about designing a /fave-eye-con/. She asked him to repeat it a couple of times, and then finally (after a convoluted explanation about favorites and icons), the lightbulb came on and she said, "Oh! you want a /fav-ee-can/!"
Now, presumably the design person is the one more likely to have encountered the accepted pronunciation of favicon - she gets to actually make the things, while the rest of us only notice them if they're missing. However, /fav-ee-can/ just... doesn't work for me.
Is there any sort of consensus on how this word ought to be pronounced?
