Look up directional boring contractors in your yellow pages. They
are equipped to shatter the existing pipe and swage in new pipe.
They usually do this outdoors where their machinery fits. I don't
know about your basement situation, but they are still where I
would start.

Waste line from house to septic tank is old (I'm guessing this
tank was
put in in the late 20s/early 30s) and runs through concrete
basement
wall under(!) an enclosed porch to the tank. Overall length is
roughly
8-10 ft.

Problem is there appears to be one area which is at least
cracked and
while is still functional at present and open am afraid this
isn't going
to last.

Does anybody here know of possible way to successfully line one
of these
suckers or other way to repair this that would save a _major_
effort to
otherwise replace this beastie at some time?

OBTW, it's a 3" line and is roughly 3-4' below grade.

Have access via a cleanout at the inside end which is a straight
shot
down the line. The tank has baffle so that is only about a 3'
clearance
on that end which makes access at a fairly sharp angle.

The problem spot seems to be roughly 3-4' from the exit end.
