 This paper reports on our ongoing project to use TCPA to transform a
 desktop Linux machine into a virtual secure coprocessor: more powerful
 but less secure than higher-end devices.  We use TCPA hardware and
 modified boot loaders to protect fairly static components, such as a
 trusted kernel; we use an enforcer module---configured as Linux
 Security Module---to protected more dynamic system components; we use
 an encrypted loopback filesystem to protect highly dynamic components.
   All our code is open source and available under GPL from
 http://enforcer.sourceforge.net/
