Yes, please.

Some of you might know that I'm not from the ARIN region, but I think that
this is an important necessity for the Global Internet to be sustainable in 
the future, so I'm speaking up here.

We see an increased number of cases where Spammers find network blocks that
are not actively used (for whatever reason), register "route"-Objeckts for
them in a database that does not protect against unauthorized creation
of objects (like, in our most recent case, the RA DB), and then announce
this address space as "theirs".  The fake route: objects will circumvent
BGP prefix filters if built from an IRR DB that does not properly check
authorization for route object creation, thus enabling the spammer to 
have wide reach with their announcement.

(In case one wants to check: is one of our prefixes that
was abused that way - announced for just under one hour, but sufficiently
long to send enough spam so the complaints hit our abuse desk and made me
investigate.  The bogus entry is still in RA DB, as they do not consider
it their duty to remove it.  *sigh*)

Cross-Registry authorization will still remain a not easily solved problem,
but at least every region should have a IRR DB that has strongly authorized
data in it concerning their own members' resources - and the RIR in question 
is the only entity that can state with certainity whether or not a resource 
holder is authorized to put in routing information for a given network, or not.

Yes, and yes.  And I understand that this is much harder, but is also
of crucial importance if we want to give users of the database(s) a chance
to build proper prefix filters for customers that happen to be authorized
to announce networks coming from different regions.  Which happens often
enough to be relevant :-)
