-Sell the rights to the electronic copy of the workbooks as a package or as a separate license with trackable id's like electronic barcode signatures or some other internet tracking signature. Other ways of making electronic copies of the workbooks only accessible to the purchaser of record: -Limit the electronic copies of the workbook to 2 x the number of personal purchases of the workbook-linked to 2 electronic licenses for each workbook purchased-verifiable by order number+ip address+username+password. -Limit the electronic copies to 1 x the number of workbooks purchased by commercial purchasers-linked to an electronic license for each workbook-verifiable by a commercial license # + documented employee credentials (verified against commercial licensees verified current employee status) + username + password. (I doubt seriously that many people would be willing to give up their usernames and passwords to third parties). -It would be impossible for a third party to be able to broadcast the ip address of the network of the original purchaser. -Only the original purchaser could submit changes to the ip address, verifiable by supplying the original ip address + some other factor like router signature/serial number or some other network signature trackable by Serif Labs when you log in. -Make the electronic copy of the workbook an online workbook whereby the purchaser of record has to log in which gives Serif Labs the opportunity to compare the ip address, username and password with the last used credentials and/or the last ip address used to access the electronic copy.
