From page 6 of Microsoft’s EULA for Office 2010:
HOME AND STUDENT SOFTWARE. For software marked “Home and Student”
edition, you may install one copy of the software on up to three
licensed devices in your household for use by people for whom that
is their primary residence. The software may not be used for
commercial, non-profit, or revenue-generating activities.
I’m pretty sure Adobe has similar terms for the educational versions of their design apps. It’s not exactly analogous to Apple’s iBooks Author terms, because Microsoft and Adobe allows full free commercial use upon buying the full-priced editions of their apps. Apple has no commercial edition of iBooks Author. Adobe and Microsoft want you to buy their software; Apple wants you to sell your book through iBookstore.
Update: Via Twitter, several DF readers report that Adobe’s educational license (see section 16.3) does not place any restrictions on commercial use.
Update 2: Looks like I was right the first time. Also via Twitter, Weldon Dodd points to Adobe’s EULA web page, which states in Section 3(f), under “License Restrictions”:
(f) Education Versions may not be used for, or distributed to any
party for, any commercial purpose.
