I guess that is feasible, I don't see why that isn't doable in future releases, as it isn't a feature now. There is an "Ideas" section on these forums where you add feature requests to future releases, and if its deemed a good and plausible function, it would get added. Perhaps a WDE-RECOVERY AD group that you add your required personnel into in the event of requiring access in an offline scenario.

There are of course lots of security concerns behind this and would have to be fully logged and documented as soon as that machine gains access to the PGP Universal server again, otherwise it would be a very big security hole if it doesnt get logged.
As for this bug, wait until a Tech Support person looks at this thread, they will be able to investigate the bug and report it if its reproducable in their environments.
