Can this be done?

At the least, you could use the ExternalInterface to get stuff via JavaScript.

Yes. In Actionscript 3 (not sure about 2) you can use the ExternalInterface object to execute any Javascript against the DOM of the page your Flash app is placed on.

ExternalInterface also gives the Javascript on your page the ability to call functions in your Flash app.
