Thanks for the information- I will definitely keep it in mind.

came up with the result that replacement within a month or two was the
most cost-effective, using one of the following technologies:

http://www.perma-liner.com/lateral.html

Note:
Both above technologies need to feed something through the existing
pipe, which is not possible once the pipe is collapsed. After a
collapse, there is no option but to dig out the collapsed portion.

I had the pipebursting one done. Replaced 10 ft of cast iron and 50 ft
of badly rooted terracotta. The new lateral will probably outlast the
house.

Both of those links above show a pit dug next to the house. In my case,
it made more sense to cut the slab floor of the basement so as to pass
the new pipe under the foundation. That was a 4 ft deep hole, as
opposed to 12' deep in the front yard.

To research this yourself, search terms for Google are

sewer lateral
trenchless
no-dig
pipe-bursting
relining
cured-in-place liner
CIPP

in various combinations.
