On the topic of charging for originally free information.

Once upon a time a local computer-magazine decided to save
a lot of money and better there service by printing answers
which had been posted on the net, in the front part as
responses to questions posed by readers.

The authors of the original answers naturally were not paid
for the work the magazine had saved.

At the same time people who write answers in newsgroups
generally do so with the knowledge that other people are
likely to answer some theirs in future as they have in the
past. This is generally not the case when information is
being sold, as on a cd or via magazines.

On a side note you'll notice that many authors have
   taken to adding Copyright or similar notices
   to their header files, as this exactly states 
   the legal position for potential misuse.

Cheers
