Seriously, I have no idea what the font is on there. Can't say I've ever seen it. I'm sure someone would have said so by now if they knew, but this one seems kinda obscure. If I come across it I'll let you know.
It might not be a font. Sometimes people modify or create their own letter forms and having to make 6 letter forms is substantially easier than 26 upper and lowercase letters plus symbols, plus kerning and letting information for a whole font file. If you really want the forms that badly it shouldn't take you more than 10 minutes to trace the current letters out and from there extrapolate your other letter forms that you need.
Almost forgot about that, too. Like in Freehand, if you convert the text block to paths, then from there you can edit the points the way you see fit and virtually "create" your own font...sort of, obviously not creating every letterform as John G said but still it's a handy feature nonetheless. Sometimes doing that is quicker and less frustrating then hunting down a font.
You should allow access to the cumulative results for those who've completed the survey. If someone takes the time out to do a lengthy survey with a lot of thought involved, there should be some pay off...
