    Thanks for all the responses...
    
    Imaging Security:
    Yes, netcat pumps all those bits in the clear, to prevent interception...
    
    1.) Disconnect host machine from LAN and use a private hub, might be a good
    idea if you suspect compromise regardless.  Thanks Jesse.
    
    2.) As Shawn said, use cryptcat.

    Dangers of dd (aka. Delete Drive)...
    It only takes one typo to ruin an entire drive with dd (like dd of=\\.\C:
    instead of dd if=\\.\C:).  I'm using two unused partitions for testing.
    
    Imaging a drive...
    Replacing "if=\\.\C:" with "if=\\.\PhysicalDrive0" on the  windows side.
    Thanks for the info from Mr. Syring... and thanks for porting this dd.exe.
    Replacing "of=/dev/hdb1" with "of=/dev/hdb".
    Again, dd is dangerous and now your entire drive is vulnerable to a typo,
    and not just one unused partition.  I have NOT tested this.
    
    Other Stuff:
    I'm using netcat 1.10 on the windows side (latest from @stake's website) and
    1.10 on the linux side.
    I never could get to trinux... maybe someone upstream from me has issue with
    Trinux :-).
