Seriously though, there has been discussion on FT recently about this. And, some FT'ers have brought up serious points:
1) What if the agent sees confidential business documents? Especially IPO/Stock/Insider Trading related
2) What if the agent insists on looking at documents covered by attorney-client privledge

The consensus was (IIRC), that Border Agents can pretty much do whatever they want "they 'own' you". For case 2 (again, IIRC) there was some discussion about whether an agent seeing the files would waive/damage a-c priv.

My opinion is that if you have *anything* that you would prefer not to be seen by "people" (whomever they may be), an encryption solution would be a good idea. Note: the agent will probably make you open up windows/os x/etc, so whole disk encryption may not work. Programs like Truecrypt (free) offer excellent encryption, and allow you to make "hidden" containers.

Basically, Truecrypt works by making a container, which is a set size (1 MB, 50 MB, 500 MB, etc.) You "open" it by mounting it to a drive letter, then you can drag-and-drop between your desktop and the drive just like if it was another hard drive. The "hidden" portion actually resides inside another container. Basically, if the agent finds the file, and somehow figures out it is encrypted, you can use another password to show them "fake" files in the container, while keeping the "hidden" portion hidden.

Hope that helps
