Hi David,

I wouldn't consider this method safe at all; a user could easily craft
their own pickled data that does something nasty and edit the source
of the form page to post it to your server.  Would it work to store a
user's prior form data in a session?  You could still use data from
the first form to generate the second page dynamically.
