Yes, I also believe the Cairo backend is the future. However, aside of the 
performance problems, there also is a correctness problem. Currently, we

I myself don't know AGG and very little of Cairo, so we'd need to find 
someone with good Cairo-fu! ;-)

BTW, Cairo also has an OpenVG renderer, which should be interesting for 
handheld devices. It's also very well optimized, so performance issues in 
Gnash would indeed be in the way it's used there.
