We run IS-IS at the University of Pennsylvania as the IGP for
IPv6. I know of a few other non-ISPs too but I won't speak for 
them. At the time we initially deployed IPv6, it was pretty
much one of the few safe choices (OSPFv3 implementations were 
very new then).

of some other than ISPs?

Even more as to which routing protocols are used, not just in ISPs, 
what percent would you give to the various ones. In other words X 
percent of organizations use OSPS, Y percent use EIGRP, and so on.

Using EIGRP implies your routed IGP dependent infrastructure is a
monoculture. That's probably infeasible without compromise even if you are
largely a Cisco shop.

ISIS is used in organizations other than ISPs.
