I have set up interdomain routing connecting both to a few peers and a
Tier1 transit provider. Not many non-research networks to be seen.
Also, since we didn't use it it kept breaking and I had to fix it every
two years or so, where it probably had been down for months.
I don't believe in Internet-wide multicast happening in current
incarnation, it's just too fragile and too few people are using it. It
wouldn't scale either due to all the state that needs to be kept.
