Not that unlikely:

http://www.ironkey.com

The Personal/Enterprise (but not Basic) models ship can act as a  
PKCS#11 token and come with a Windows PKCS#11 library which can access  
it.

It provides space to store one user specified key/cert alongside an  
IronKey generated cert on the token. I believe it's main key, used for  
the flash encryption is generated when you initialise the device

Am currently in conversation with them about when they might provide  
PKCS#11 support on the other platforms you can use these on (i.e.  
linux & OSX) - looks like they're possibly working on OSX but no word  
on linux yet. The main flash is hardware encrypted on the device. I  
presume the crypto hardware uses proprietary USB protocol...

No connection, other than we've been evaluating one for use within our  
company.
