I would like respondents to be able to draw lines to match values in two columns. The purpose is to make the survey as easy and understandable as possible for respondents.
I believe there is a software company called KnightSoft that does survey software with handwriting recognition; I'm not sure if it does what you are describing though -- although they might be willing to customize to your needs. Alternatively, if what you are describing is essentially a basic matching function, you may want to look if your institution has a license for WebCT or Blackboard or similar courseware -- those systems are designed for testing, and matching is usually one of the question types they work with (and you can set it up so that anyone can have access, not just people "enrolled in a course").
