now bowlwoman again:

No, I didn't mean the only ones to do this type of travel at all, 
just the only ones to figure out how to get around the defenses at 
Hogwarts to travel/communicate via Floo powder.  

I guess I wasn't as clear as I should have been in my original post.  
I wanted to say that Lupin/Siruis are the only ones we've seen 
onscreen do this type of travel WITHIN Hogwarts or TO Hogwarts.
