I am an author of LISPSM and I do not totally agree with your Robert. I know cases where LispSM or MSM still works better (flight sims with sparsely filled frustum). I admit LispSM has many weak points so usually do not respond to your comments but I just snapped. On that particular issue I believe that commented line 60 in StandardShadowMap.cpp may be the culprit. And no, I did not comment that line. Somebody else did and it was commited into OSG source then.
