    I'm not sure if this is really a better solution.
    The Problems I see are:
    - when the device is used it's the same as with temp/swap files on a
    - when it's not used someone could find a usb-stick lying around ...

    Using Linux I think it's very easy to implement.
    And if you delete the data on the usb-device before logoff, you could
    also do this to your temporary files or the swap-area. And with an
    usb-device you have the complication that you can't be sure that the
    data was erased. Perhaps you pulled it out a little to fast ...

    I'd prefer to put such important temporary data on an encrypted
    filesystem. But the solution I'm using right now has the disadvantage
    that after I mounted that filesystem everyone with root-privileges can
    read it. My workaround is to only use it on a system were no one but me
    has access. But the why encrypt that stuff if I'm the only user?
    If someone on this list has a solution for my dilemma I'd be very
