USB Drive Encryption for Non-Admins

Does anyone know of software that can encrypt a USB flash drive but still allow a user to access the encrypted data on a computer without administrator privileges? My first thought was to use TrueCrypt, however I could not mount an encrypted volume on Windows 7 under a standard user account. What I am trying to prevent is the access of data from a lost or stolen USB drive.

 

1)SafeHouseExplorer - windows only + when without admin rights - not really the most comfortable access to your files, but better than nothing

2)SecurStick - cross platform ,no admin rights BUT - the problem is it's slow, and requires to flush some cache with a batch file to remove traces after use

 

try "FreeOTFE explorer" from "http://www.freeotfe.org/"
it doesn't need install and no admin

Edit Post: Oh, you might also want to consider a USB drive with hardware encryption.
