You actually don't have the right to sell the software. After purchasing, your rights are to install the OS on ONE system. You don't have the right to sell or transfer licenses, because in that case you are violating the EULA.
EULAs vary by different software. There is not a standard EULA as you imply.

Most EULAs allow you sell the software as long as it's not Academic or OEM, and you include the license. Otherwise, you're just selling a media kit.
By wary on eBay for sellers that sell Academic versions of software that may not be forthcoming. Only students, faculty and teachers of academic institutions are allowed to purchase Academic software.
Many software companies such as Adobe and Microsoft label software on the box, license and media as ACADEMIC. However, Apple ships the same license, box and media to students and teachers who purchase Mac OS X from their Apple Store for Education as they do their retail customers who purchase Mac OS X from the Apple Store Online.
By the way, EULAs are not legally enforceable in the United States because customers are not privy to the EULA before purchasing the software and are not allowed to return the software to their respective retail store because of piracy laws.
Many software companies include unusual or radical wording in the EULA that prevent you from doing certain things that may violate your rights.
For example, in ACDSee 7 the EULA states that you can not use the software to look at pornographic images.
