I assume that you are trying to defeat "robot" registrations.

My suggestion, to keep things simple, is to use something like the 
system used to sign up for many mailing lists.

1) User fills in form, including an e-mail address.
2) Application sends an e-mail with
	2a) a link which can be followed to confirm the
	registration.
	2b) an instruction to do something on the page like
	"select the first option on question 3, the third
	option on question 2, the second option on question
	3".

The second option would be, in my opinion, the most robot-proof.  I 
could give you an example in Perl if you wanted it.

I use mail-generating code in a few of my applications; the e-mails are 
short and simple and thus (hopefully) accessible; less than a dozen 
lines of code are required to produce the mail (using Perl example) and, 
in my Linux environment, there is no noticable overhead on the server.

Cheers

M
