Note that first level groups (those directly on the card) will
automatically get this message, so all you need to do is be sure to
pass it in each handler so that the next group down will get it.
Be very careful sending a standard message to any object and
especially to child objects: you may find yourself in an infinite loop
if the child doesn't handle the message and it makes its way back up
to the parent object (which resends it...). It'd probably be better
to make up another message to send to the nested groups.

It should, yes.

Another feature that might be useful is the groupNames and groupIDs
properties of cards. They return a list of the group objects on that
card, so you can deal with those first level groups separately.
