We have such a proven and stable service in Europe: The RIPE Routing
Registry. Yes we could do more to get it populated better but that
is a matter of appropriate resources which we do not have at this
point. As a matter of fact I am quite envious of the amount of
money NFS spends on the RA.
We also have a number of useful tools that make use of the registry.
These were developed with money from real service providers (European
We also have a number of providers that use the registry (albeit not
exclusively) in configuring their routers. I understand from them
that it actually helps them limit the complexity involved.

Do not confuse the transport mechanism with the update mechanism.
We support only e-mail as a transport at this point and get no
flak about it because the update itself is automatic and turnaround
times are consequently low. The main factor is the e-mail transit time.

We have working code for interactive updates but before deployment we need
to solve authentication and authorisation issues. Since mail works very
well this is not a high priority at present.

We have that at the moment: Make a dump of your database in RIPE-181
format and we will copy it. It is crude. It works. We are working on

Please define secure. ;-)
We have and authorisation and authentication framework for updates.
See ripe-120 for details.

In a routing policy description language such as RIPE-181 tradeoffs have
to be made between complexity and power of expression. In RIPE-181 we
have made some design decisions towards limiting complexity. The main
reason for this is that all ISPs will have to learn the language!
The RPS working group will work to expand power of expression while
hopefully retaining enough simplicity for the majority of cases to prevent
your "implementation people dance around" when it gets replaced eventually.

Maybe you should contribute to the RPS working group, especially in the
area of suggesting features needed where RIPE-181 lacks the expressive
power you need.
