small site multi-homing (related to: Small guys with BGP issues)

While the idea of seamless routing sounds great, so does world peace... I 
don't think I will see either in my lifetime.  There are some technical 
hurdles you will have to solve first.

1st how do I solve security (preventing spoofing and other evil deeds done by 
rouge networks).
2nd how can my system scale and achieve stability.
3rd how will my routes work and converge (unstable routes don't work really 
well).
4th My system will need to work and scale on a much larger environment than a 
lab.
5th How do I test and verify your system.
6th Politics/Layer 8 (think peering wars)
7th How do I propose for routers be able to store (2^128 + 2^32) * x routes in 
their routing table, and possibly utilize current hardware (the whole world 
isn't going to do a flag day forklift upgrade)
8th How am I going to get anyone to invest money and R&D into my system.

If you have any good idea's we'd love to hear them.  I am open to such a 
system, but do not think it can realistically happen anytime soon.
