hi:

I'm a long time phpsurveyor/limesurvey fan - cf : http://blogs.zdnet.com/Murphy/index.php?p=513 .

Right now I'm on day one of a project requiring some extended delphi type studies - meaning that I don't yet have many clues about what to do or how to do it.

Nevertheless I'm looking at Limesurvey because it appears to have all, or almost all, the parts needed to do this. However, it seems there's one capability which I don't think you have that would make a difference for this use of your product.

It's a self-modifying question type: one in which the answers available to the survey taker vary dynamically with the input from other people taking the survey - vide:

1X Our consultants are recommending biometric locks for lab and office doors as well as the supplies and components cabinets. In this context, how would you rank the alternatives listed below?


1X1 Accept consultant's recommendation
1X2 Stick to existing mechanical locks
1X3 Switch to hotel like card locks
1X4 or ? _____________________________

So someone fills in:

1X4 or? replace employee cards with the Sun Ray cards, and use them for the doors too

and now I want the next person to load the question to see the alternatives as:

1X1 Accept consultant's recommendation
1X2 Stick to existing mechanical locks
1X3 Switch to hotel like card locks
1X4 Replace employee cards with the Sun Ray cards, and use them for the doors too
1X5 or ? _____________________________

With some mechanism to keep the list from growing off scale - probably a question set-up switch setting how many can be added before something changes. The change choices might then be (where N is the maximum number of alternatives to be shown):

1 - select N randomly from all alternatives;
2 - select the N alternatives with the most votes;
3 - keep the original alternatives constant, select the remainder randomly from the suggestions;
4 - keep the original alternatives constant, select the remainder according to the number voting for each suggested alternative.

is there some way to do this (or something close enough to it) now? and, if not, how hard would it be to make this possible?
