[Laszlo-dev] Are there any tricks I should know about lz.embed?

[P T Withington]

Yeah, I see that I can broadcast a call to all the swf apps in a page,  
but it seems that there can only (currently) be one DHTML app in a page?

I will just write separate methods for swf and dhtml for now.  I think  
I am close to having it working.
