Huh?  Where did you see "education" in terms of service contracts?

If a person goes in the business it is assumed that (s)he knows
the profession.  It is certainly not the case for many US-based Internet
service providers.

The problem is that even a tiniest service provider doing BGP with
some bigger provider can kill most of the Internet by injecting
a single bogus route.  (I expect to hear more "RS will fix everything"
speech at this point.  Relax.  It is not here yet; and we had occasions
when bogus routes were killing ANS connectivity per-network filtering
notwithstanding.  There are bugs and interesting incompatibilities :).

Such service provider doing multi-homed trick is simply a walking
disaster.  That's why we're making sure all parties involved understand
the routing policy, safe networking practices, etc before we enable

Sounds kind of over-expectant.  Considering that even large service
providers have real bad problems with finding engineers who know
what they are doing.

The best we can do is to limit the damage by doing fascistic filtering,
and work with those ISPs who want to listen and really want to learn.
Others will be out of business earlier or later anyway.
