Another example of abusive license:

"If you need to install your software on a new or different computer, you will need to re-activate the software on that computer using that serial number. [..] This contacts the MacKichan Software licensing server, which we will keep running for at least two years."

When the open source project for Scientific Word is established, an announcement will be made here."
