Oh good deal!  Thanks for pointing me to Wikipedia on the subject! 
Wikipedia always a good refresher of way more than one needed to know or 
had time to read ... :-)  Further reading suggests that Phil was indeed 
infringing on SEA's work, but that the Zip file format is *not* the Arc 
format.  I agree with your conclusion that Zip certainly started life 
because of Arc and an associated interaction, but like you, I don't know 
the internals of the formats.  I had recalled that there was a 
controversy at the beginning, but I thought it had long been resolved. 
Surely the Free software community, especially as small as it was back 
then, would not have let illegal IP into its ranks?

We're rather off LibreOffice topic at this point (my fault!), but I'm 
still genuinely curious about your comment that Zip shouldn't be on a 
*nix system.  It's not the first time I've heard that opinion, but it's 
the first time I've probed further.

Thanks,

Kevin
