1)what are the zombie agents for in the listed shop miniatures?  Are they for a
ruleset I missed or perhaps something that is coming up?

2)any thoughts on giving an alternate time for playing Hour of Glory:
Stronghold?  Updating the time to now and using some extra gadgets for both the
spies and the building guardians would be interesting... for a non-lethal
alternative for the spies you could use gas grenades, dart pistols and either
knuckledusters or saps.  Cameras, pressure plates and eye/fingerprint/voice
readers could be used for the building guardians...

Just a thought of course.
