One detractor, to the best of my knowledge, is that the route servers are not exactly 'dynamic', meaning that they are updated a couple of times during the course of the day to reflect any changes in routing policy. Therefore, the possibility for blackhole'ing packets exists.
I'm sure someone will correct me if I'm remiss. :-)
Yes, I will do that:-) Route Servers are dynamic, they process upto 6000 routing updates a minute (see http://compute.merit.edu/stats/mae-east/instability). Route Servers are reconfigured with up to date policy 6 times a day, i.e. every four hours. Hence, a brand new route registered in IRR may not be announced by the route servers to the NSPs whose policies are prefix based for up to at most 4 hours. I think this is what you are referring to.
