I'd encourage those of you who are interested in this topic to read RFC 2650 (ftp://ftp.isi.edu/in-notes/rfc2650.txt) and start working to using RPSL for this task. It seems really strange to have filter lists (in proprietary format) flying around to achieve this.
Registering your routes in the IRR (www.irr.net) and then using a mailing list to say "we've changed our details, see the registry" looks like the way to go. APNIC have a pilot service running which ISPs from this region can use.
