2. It only protects you from failure of a link from you to upstream, not from upstream losing their connectivity, power, or flapping like crazy and getting dampened. In my experience, latter happened more often than first. :)
note that "non-direct ebgp" peering on the picture can actually be between e-br-a and *any* router in isp-b, not necessarily isp-br-b. this way your real problem 2 is solved.
Not really. If the 'internet defaultless core' routers drop the route to ISP-B, then you are still completely screwed.
oh, yeah. also, if isp-b gets suddenly evaporated, then i'm screwed even more... :) anyway, i think it would be safe to conclude that the answer to my initial question would be "no".
