If you present a common goal along with a list of things we're  
allowed to break, coming up with a new routing protocol that better  
meets these goals than BGP won't be too difficult. Shoehorning the  
changes into BGP would be harder. Deploying it a challenge. But the  
real problem is agreeing on the goals and throwing out current  
"features".
