Lindsay, FYI, our upcoming FormsPlus library will allow prefill on non-Marketo pages. If you're interested in joining a Beta, contact me at https://purechat.me/sanford.
P.S. I never bought the security concerns explanation. It's more likely that your external website is running SSL than your Mkto LP domain (considering the setup cost) and posts from http://landing.example.com aren't forced over SSL.
I am VERY interested in this. When were you guys launching this?
Amy, I just followed you on the Commty. If you follow me back and PM me your details, maybe we can talk for a few minutes. Bottom line: functionality exists, packaging it as a standalone library may not happen but I can link you to the code.
Follow me back and we can chat about it!
P.S. I've had an HDIM trial sitting by my desk for months.
