while the respondants are discussing the subject, a researcher creates a copy of survey 1 (= survey 2)
each question of survey 2 is the same as survey 1, but the results (percentage + chart) of the same question in survey 1 are shown, so that the respondant knows what was answered in the survey 1
In general something like this isn't easily doable using Limesurvey. For security reasons you can't access survey data of survey #1 at a second survey.
The only solution I can think of is using custom coding based an an Ajax request at survey #2. That ajax request calls a PHP script which can then read the data from survey #1 and output some charts or results directly at survey #2.
