Hi Graham

Based on your description of what you need, you'll probably want to set up
a lightweight server with a wireless adapter or linked to an existing
access point via an ethernet connection - you'll also need to find some way
of sending the delegates to the questionnaire as an initial page.  While
this can be done using netfilter, it's not exactly straightforward.

Perhaps a good starting point would therefore be some form of captive
portal (commonly used for authenticating wireless guests in public
hotspots) - as these are usually configured to redirect guests to a
login/entry page.  I've only ever set these up on *BSD's so probably
wouldn't be much help here - but a quick search led me to
https://help.ubuntu.com/community/WifiDocs/CoovaChilli which looks like a
good recipe to get you going....

Hope this helps
