The idea would be that you do a layer 3 protocol only on a few selected 
"gateway" nodes of the clouds. Those gateways would forward traffic from one 
cloud to the other, without having the details (and thus not having the 
overhead) of the state of the mesh.

Which technology is the best is beyond my knowledge.

Cheers,
