Robots and Copyright

Does anyone who teaches web programming integrate a discussion of copyright?

I found this necessary to do after answering student questions after 
my lecture on web robots and /robots.txt.

Students wondered how far they can go their robots -- can they pull 
down graphics, can they pull down whole pages, how much, how little, 
do they have to always read the copyright notice on the web site?

These questions lead into how much their final project can do, if 
they choose to build a robot or make a portal.

Does anyone tackle this formally or do just say "be careful" or 
"don't get caught"?

I've been given a book called "Computer and Internet Use on Campus: A 
Legal Guide to Issues of Intellectual Property, Free Speech, and 
Privacy" by Constance S. Hawke.

I've also noticed that students knowledge of these issues parallels 
their what they've experienced under the Copyright acts of 1909, 
1976, and the DMCA.  You might divide it into those who draw 
parallels based on printed media (i.e. 1909), music (i.e 1976) and 
electronic media (DMCA).
