Modal FBA Login

Hi all,

Using Forms Based Authentication(FBA), is it possible to deliver SharePoint Login via Jquery Dialog box or any other modal mechanism. I basically need to prompt user to login but i know sharepoint requires that the authentication happen through the login page via inherting fromMicrosoft.SharePoint.IdentityProvider.FormsSignInPage, i was thinking of using iframe to do this, but not sure if there is a better way?

This is a very custom site with custom master page, no out of the box.

Thanks

Al
