Multiple Respondents for One Survey Submission?

Does anyone know of a way to allow multiple respondents to complete only one survey and then also see (while completing the survey) the responses for their fellow colleagues who already answered that question? The situation is that our new customers have within their own organization, multiple employees that will need to assist in the one survey response. Since we don't always know which new respondent is the "who" that will have the answer, we need multiple respondents to be able to view the response previously submitted by their colleagues. Thanks in advance for any suggestions you can offer! Unfortunately, breaking up the survey into parts of a whole is just not an option.
