Memory intensive:

root = container.restrictedTraverse('/')
for path, ob in root.ZopeFind(root, search_sub=1):
     # do something

Requires two Scripts:

root = container.restrictedTraverse('/')
f = context.myScriptThatDoesSomething
root.ZopeFindAndApply(root, search_sub=1, apply_func=f)

Recurses once:

##parameters:ob=None,path=None
if path is None:
     root = container.restrictedTraverse('/')
     root.ZopeFindAndApply(root, search_sub=1, apply_func=script)
else:
     # do something
