Randy,
A part of the IIRToolSet is peval(1) which does exactly what you ask. It
can expand an as-set or an aut-num object in a single call. For the RADB
servers it works fine. For the current RIPE software just add "-protocol
bird" to the command.
% peval -h whois.ripe.net -protocol bird AS-CERN

IRRToolSet is a part of the FreeBSD ports collection and is currently at
version 4.7.2. I maintain the port (but not the actual software), so
please let me know if there are any problems.
