SWF text preview of html form

Hi everybody...

Can somebody please advise if this is possible with SwishMax? What I am trying to build is a live .SWF text previewer of what a user is typing into a HTML form, where an 'Onkeyup' event would (presumably) update the .SWF preview pane.

Basically imagine yourself personalising a postcard online, you have a view of the actual card on the left and a HTML personalisation panel on the right. As you type the preview shows the text. Unfortunately, the text input has to come from within a html form. Id just love to have a SWF preview panel because I can embed fonts etc.

Any advice or a link to a tutorial on this would be fantastic!

thanks in advance
