In our shop, compliance sits in on all the BCP sessions, planning and testing.
On a related note, this year we moved away from having 8,000,000 separate contingency plans (pandemic flu, pandemic flu during a snowstorm, pandemic flu + electromagnetic pulse, etc.)to classifying the effect; access to workplace, access to systems, access to communications network, for example. You can still have a good time spinning the big 'wheel of misfortune' if you want, but your reactions are all going to fit in broad categories (did our office close? did the one on the west coast close? do we still have access to our systems?)
