    Wouter & Craig,
    
    The pi-getram utility in the pilot-link package dumps the full contents
    of RAM from a Palm device. Therefore, this may not work with Psion Revo:
    
    # pi-getram /dev/cua0 ram.dump.081301
    
    There are tools available to law enforcement that allow for more
    advanced analysis of a wider range of embedded systems. I expect that
    these tools will become more widely available as the need increases.
