Protect your data from yourself

Schneier talks about dealing with customs computer searches by encrypting your data with a random key.  It occurs to me that having Windows Home Server provides an easy alternative : don’t take your data with you in the first place.  Bring a throwaway netbook instead, and connect back home over the SSL VPN that is WHS remote connect, to get your data.  Save your data back over the VPN and if the Netbook gets impounded, just buy another one.
