Denis,
I found a partial solution. I think. :silly:
0) Set up your survey to use tokens.
1) Set up a user group and add that repondent name to it.
2) Restrict permissions for that user such that he can only view and updates responses.
Of course the problem is attaching that respondent's token to the data entery screen so he can only view his response. He can change any response he likes! Is there was a way to use a query string to limit this?
Code:

I'm still in 2.00+. (Waiting for comfort update!) What do you think?
