Newbie question: Assuming a multihomed environment with N ISPs

multi6 proposing that the interfaces of the routers and computers
each have N different global addresses, one set for each of the N
ISPs?
At this time, multi6 isn't exactly proposing anything. But yes, pretty
much everything that's under discussion right now assumes this.
If so, has multi6 considered the impact of this approach to IGP and
EGP performance? If so, what was the consensus conclusion to that
evaluation?
There hasn't been an evaluation.
There is a feature that I'm very much in favor of that could help
here: the ability to implement a multihoming solution in middleboxes
or border routers. In such a scenario, there would be a set of
addresses for internal use in the site, and the proxy multihoming
devices add the multihoming capability somewhere close to the border
of the network. The good thing here is that there is no need to modify
each individual host to obtain multihoming benefits, and it's easier
to implement policy in a few central places rather than distributed
over all the hosts in the network.
