One page, two forms, two recaptchas

Hi. I need to have two different user registration forms on one page, each with it's own recaptcha....which does not appear to be possible. The second form displays a blank where the recaptcha should be. To answer the obvious questions in advance, no the forms cannot be on different pages (the entire site is protected with the Page Security plug-in so non-authorized users are redirected to this one page to create an account. There is no way to grant them access to more than one page) and yes, both forms are needed (for two very different kind of users). Really need to have two recaptchas on one page, or have both forms somehow share a recaptcha, or ??? Thanks in advance! (I don't speak geek very well so simple explanations are best for this unfortunate, accidental webmistress)
