Are you aware of RtConfig whcih is part of the IRR Toolset?
( http://www.ripe.net/ripencc/pub-services/db/irrtoolset/index.html )

RtConfig is used to generate router configurations (or parts thereof)
based on the "whois" info.  As such, it is concerned with routing aspects
only and focusses on proper "route objects" in the whois database.  It is
not concerned about inet-num objects which document ("should document")
end-user assignments.  Nevertheless, it might serve you as a good model
for, say, a mail filter based on whois checks.
