Well, it's not really all that hard.
Googling ZopeLabs turns up a bunch of potentially relevant recipes.
...although, i cheated and searched for the method names because
I already know what they are :-)

for any PropertyManager)

That's not so unusual.. see for example CMF and all its offspring,
e.g.CPS, Plone....

to all of 'em? Traditionally we do this sort of thing via an
iterator script. Something like:

all = context.ZopeFind(context, obj_metatypes=['Formulator Form'],
                       search_sub = sub)
for form in all:
    form.callSomeMethod() # i'm too lazy to look up the formulator API

yep, there's no free lunch with that kind of problem.
