I have a suggestion to "kick it up another notch" I've done this already on my site, but I didn't want to step on your contrib, and you're probably (when I say probably, I mean you are) a much better coder than I am.
Here's what I did. I made the textbox for "other" populate if it has anything in it at all. I added other/referral and a tiny note that if they were referred by another customer to enter the name into the box and they will get a gift cert for referring them after their first order (they must be a member that has placed an order also)
I added the code to admin side customers.php to see if they were referred (=4) and if so, the name of the person, makes it easier for me to track it and who to send the gift cert to.
It wasn't too hard, and of course this is only for Strider's CCGV, but it was just a thought...
