However, if a different third-party network then sweeps up their routing table by looking to remove more specifics that seem 'spoofed' using IRR data, the routes you intend to push onto the internet may well start to disappear from their perspective.

I don't think this should be possible if the database implements RPSS (RFC 2725) properly. I believe that it should only be possible to create a more specific route object with the agreement using whatever PGP/X.509 security you like if you have used mnt-lower and mnt-routes attributes as appropriate.

I'm not sure I'd want to publish my routing policy in a database that didn't have a reasonable implementation of RPSS.
