Feature Request: tokens for authentication

Hi,

I'm not sure "tokens" is exactly the word for this, but here's what
would make Mod_survey *really* user-friendly for me :).

The biggest problem I have is inviting participants to a survey. If I
want it secure I can use username/password combos, but this introduces
the possibility (likelihood) of user error. What would be cool would be
if I could provide a list of email addresses and then generate tokens
for each user. Then an email would be sent to invite each person, with a
link to the survey that includes their token, i.e.
http://www.survey.com/election.survey?token=1234567890. No token or
invalid token, no survey. If that user's token has already completed the
survey, no survey. (The possibility should still be there to allow
anonymous and multiple submissions, of course.)

I have to confess that I disovered this while visiting PHPSurveyor and
playing around with the demo there. I still prefer Mod_survey, but this
token stuff in PHPSurveyor is really slick.

Would this be difficult to implement, or is there some other security
consideration I'm missing? Thoughts?

Best,
Todd
