Apple's end user license agreement for the iBooks Author app has generated extensive controversy among authors and publishers. Namely, the agreement restricts paid distribution of "works" created with the software to the iBookstore only. Technical limitations may make the restriction a moot point for the time being, as only Apple's own iBooks apps can even read the files generated by iBooks Author. But forcing users to sell content through the iBookstore, governed by a separate contract with its own terms, might not survive an antitrust challenge in court if it were to come up.
First, it's important to understand two aspects of iBooks Authorone technical, and one related to its license. The iBooks Author EULA has a stipulation that limits paid distribution of iBooks created with the software to the iBookstore. If you create something with iBooks Author and give it away, there are no limitationsput it on the Web anywhere you like. If you want to charge people money, you have to use the iBookstore and Apple gets a 30 percent cut.
