I wrote vvvv.

     I'll see
about trying that tomorrow.  I don't really mind if it takes 
 days to copy (I'm moving a 300+MB image) as long as it's error-free. 
   That won't fly.  VTserver v2.x has a 32MB file-size limit.  :( 
Use Vtserver to install an OS and use that to do the heavy lifting...

HOWEVER: RT11 has a 32mb limit (per file device) as well so use an 
OS that can handle that size files.  Maybe UnixV6 is a possible choice.
