There is an interesting lawsuit going on that would test the limits of the 'tresspass to chattel' law. (details here). Unlike EFF, I do think that Intel should have the right to legal recourse to stop Mr. Hamidi from sending those e-mails. But I don't think the application of 'tresspass of chattel' laws here is a hot idea. That statute is already being badly misused. I would try to find some better links later. 'Red Herring' has a good story on the subject on its print edition.
