When I was doing LM-PCR a few years ago, I used the original Mueller and
Wold protocol (Taq polymerase, increasing Tm's of nested primers, P3
end-labelled with P32) with no modifications.  Can't remember offhand baout
overlapping primers, but I think P# overlapped P2.  Upshot was -- it worked
beautifully.  I can mail you reprint if you want, or just the reference.
