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&restart 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.
