The definitive answer to this can only come from the Wolfram licensing folk. I suspect that the real legal bind in the Home Version use license is how Mathematica is exploited. I have actually read right through my own home user license agreement and the key points are to do with commercial benefits that may arise from using Mathematica to solve problems.
In my last career post, I was involved in managing the licenses of specialised engineering packages used by maybe less than 1% of the engineers in a globally operating, oil company and it was a real pain. The $ cost to go from a single desktop user in London to roam anywhere was significant but made life simpler as we were commercial users.
Marc if you are a 'hobby' user like me then I imagine you won't have a problem with the Wolfram IP people. On the other hand, if you are using Mathematica to support a business, whether it crosses national boundaries or not, then you are looking at the wrong licence to start with in my opinion.
