HI Bruce Thanks for your comprehensive response. I will take a look at Vernor v. Autodesk - it looks as though there may be quite a big difference in practice between first sale in the US and exhaustion in the EU: more that I had anticipated.
I very much agree with your practical approach. In reality, it's unlikely that anyone will pursue a GPL violation claim very hard so long as the (correct and corresponding) source is available easily from somewhere. All the best Andrew Andrew Katz Moorcrofts LLP
