Book 6 title

Hi all,
I keep wondering on this whole 'book 6 title hint' and I might have found something. It could be a red herring of course - I wouldn't have paid any attention to it if it wasn't for the rumours. Anyway, from 'Careers Advice' 
"(...)Sticking his head into the fireplace, he took a large pinch of powder and dropped it on to the logs stacked neatly beneath him. They exploded at once into emerald green flames. "
It's the 'green flames' thing that made me wonder. A green flame torch could be some sort of transportation device? Could book 6 have something to do with being able to go here and there easily through Floo or whatever? 
Or am I too obsessed with the title issue? :)
Cheers,
Julie
really glad she was able to use the expression "red herring" for the first time in her life - JKR taught me this expression!!
