Sorry to respond to such an old thread, but I would like to voice my concern about getting Orion and Cirrus IPv6 capable. There is a mandate that by mid-2008, U.S. government agencies are to have their backbones fully IPv6 capable. As a service provider, we are joining in the push to generate IPv6 interest, so we need our tools to be v6-capable. Even MS turned on IPv6 by default on Windows Vista. Let's put this on the roadmap - it can't be terribly difficult.
It's on the roadmap, but I don't have a firm date. \
