Password protection of USB version

I know that I can export Opus to truecrypt image and then I am safe in case of pendrive lost. BUT this is not so easy to run that pendrive on some machines (especially machines with paranoid AV/system settings). In fact, simply protection of starting Opus by password will be nice and safe enough (I think that 99% of people who find my lost pendrive are not hackers who can extract my FTP passwords - for example). This is just suggestion but will be very nice if password for startig Opus will be implemented in some future version.
