    Out of curiosity, what would happen if one of the parties got transit
    from a business POV? Not just in this particular case, but in
    general.

    Doesn't this work because they are so large that any such arrangement
    would immediately threaten traffic ratios at the (transit-free)
    transit provider?

    > 3. Standard transit contracts do not guarantee full connectivity

    If this were true, why would end users (or, more generally, not
    significantly multi-homed networks) buy transit from such networks?
