Sounds like you're starting to reinvent the I-Button.
(Dallas semiconductor's product - uses a small computer chip
and an infrared link attached to a watch battery.)
But, yeah, the USB memory things are cute, at least if you're
using machines new enough to have USB ports.
If your threat model includes people rifling through your office
looking for stuff, you're probably toast anyway,
but you can always do a secret-sharing thing.
If you do want off-site storage for your keys,
secret-sharing is especially important.
