Thanks for the reply.
Just to clarify, it was never my intention to get around any copy protection or anything like that.  
I too am of the view that it is fair use if I install a game to my two PC's and invite a friend to play.  However, if the license agreement forbade this I would just be less likely to buy the game - I wouldn't lose any sleep getting aggrieved over it.
Does anyone from Shrapnel read this forum? If so, would they mind stating their position on this?
A good example of a fair solution for LAN games would be the Last game I played and genuinely loved, which was Total Annihilation (yes, I don't play many games  

  ).  With TA you could install as a multiplayer spawn.  Actually, IIRC you could do this even for Internet play but all my friends bought a copy anyway so they could practise against the computer  
 
 
Actually, I've thought of a better question.  Can my friends get a feel for the multiplayer game using the demo?  If so, would I have to play the demo too and could we continue the same game if we then purchased it?  Phew, hope that makes sense!
I have now downloaded the Gold demo by the way but have only had time to play a couple of turns.  I also didn't read the FAQ so I have colonies with no population on them  
 
 
Reading threads like the 'Proportions Mod' makes me want to like this game...
