Well all these binary only drivers are just causing more people to
reverse the technology and in doing so gain more insight than would have
occured if an uncommented free driver exists. Novell's attitude has put
almost the entire Novell protocol into the public domain and caused GPL'd
Novell server clones for example.

The floppy controller tape interfaces are documented. Hence ftape.
