Now that's very clever! Shoot, you could post those to a public website 
in that case, then kids could download from home.

Of course, teaching teachers (I'm not worried about the kids picking it 
up) to use encryption tools is probably more work than maintaining all 
of those unique groups :)

Hmmm.

Actually, it should be pretty trivial to write a script that would 
automagically encrypt a file with a public key, and move it into a 
public folder.

If you could teach the teachers to properly name documents (for example 
"jsmith2006-Horse Report.doc"), and then have them drop the file into a 
holding folder, you could then have a cron job run all day watching for 
files in that holding folder. It could then parse the username, encrypt 
the file, and move it to the public folder. Then you'd only need to 
teach the kids to unencrypt their work.

Interesting idea!
