Ah. Thought you were talking about Droid.
Where iOS is concerned, if the maximum number of free developer codes is exceeded nz17 can just send a "gift purchase" of the app to anybody who pledged, cost for that can come right out of the development fund, and if he starts off the pricing of the app with a launch sale within the first 24 hours or so, it can even minimize that as an expense.
There's always creative solutions where these things are concerned.
