It's my understanding that "B'Shalom" is a greeting for the dead, as in "My aunt Bertha was a wonderful woman...B'shalom." (Meaning, roughly, "be at peace" or "rest in peace"). "L'Shalom" is, I thought, a greeting for the living, as in, "I hope your week-end is a good one. L'Shalom." (Meaning, more or less, "wishing you peace.")

Any thoughts, input?
