You're right:  a database that is not used becomes out of date.
There are a few things that will encourage ISPs to maintain up-to-date
data in the IRR registries:  

  1) The availability of useful tools (such as prtraceroute) that will 
     only work correctly across you network if your data is registered
     correctly.  (Even if you don't use these tools, your neighbor ISPs
     may start sending you prtraceroutes across your network that show your 
     routing or your policy description is wrong).

  2) The registry is the method by which you specify your policy for
     the Route Servers (if you use them).

  3) Some other major ISPs will not route nets that are not registered.

(Note:  the RADB is one portion of the Internet Routing Registry (IRR),
which is composed of the RADB, RIPE, MCI, and CANET so far.  Registering
in one database will soon be sufficient for all purposes globally).

The email interface to the RADB and IRR is one that has been running at
RIPE for a couple of years (also an email/template interface).  RIPE's
user community lists improving the user interface as a rather low
priority.  Nonetheless, the code is structured in such a way that
telnet, web, or other interfaces would be extremely easy to integrate
(once authentication was established).   What kind of interface would
you like to see?

Updates to the registries are processed and confirmed within a few
seconds, and are immediately verifiable by whois query.  How often
ISPs choose to regenerate their config files is a separate question.
(I think everyone is planning updates more frequently than twice per
week now).

If you want to add a net to the IRR and then have that change immediately
reflected in the configuration files of all ISPs who do full net-based
filtering, you may have to have some discussions with them.  (But the
data will be there and waiting in the registry).

I'm not sure what you mean by this.  If you issue the command:  "whois
-h whois.ra.net <net>" right now, you get the registrations for that
net from the PRDB, the RADB, the RIPE database, MCI's database, and
CANET's database.  If you register in the RADB (or the PRDB, for the
moment), then your data is available at the other registries as well.

This has lots of aspects.  We have implemented PGP for the interface
(not yet released), and are working with the CERT to establish that
other security concerns are addressed.  More specific discussion is
welcome on a smaller list.

Yes, we were listening in Boulder.  Some enhancements (to support
AS-path expressions) have all ready been coded, and Cengiz Alaettinoglu
and Daniel Karrenberg have all ready set up an IETF working group with
an aggressive schedule for implementing for an enhanced language.
(An early version of the implementation is started, I believe).
