"Flash activity" as in "activities that occur within a SWF-based interface element"?
If that's what you mean, it's very simple to use the Flash-object-to-HTML-document bridge (ExternalInterface) to call JS functions. Of course your SWF element must support such interaction, but it's not the HTML part's fault if it doesn't.
Yes, that's correct.
