I was thinking of a scheme by which the ISO is constructed and streamed
at the same time, so the complete ISO images aren't ever stored whole
anywhere on the server.

Very good point.  I did not consider the interrupt issue.

I'm not sure I understand what this means, but it does sound like it
implies that streaming production of ISOs is technically possible.

I have such a macmini-1,1 which I upgraded to macmini-2,1 (it's the same
hardware and the firmware upgrade was needed for one of the other
upgrades (can't remember if it was to bring up the RAM to 3GB or to
upgrade the CPU to a Core 2 Duo)).

[ It's my office desktop, happily driving two 1600x1200 monitors (with
  a DVI-I => DVI-D + VGA splitter), something which Apple's own OS never
  bothered to support.  ]

But IIRC I install Debian on it by cloning some existing Debian root
filesystem directly onto the drive, rather than doing the "normal Debian
install".  So don't make those extra sets for me.
