Is there a way to get a list of all currently instantiated objects?
Can that list be made to send an event/message asynchronously whenever it changes?

The ObjectSpace module contains a number of routines that interact with the garbage collection facility and allow you to traverse all living objects with an iterator.
ObjectSpace.count_objects
# => {:TOTAL=>56824, :FREE=>7190, :T_OBJECT=>5943, :T_CLASS=>878, :T_MODULE=>35, :T_FLOAT=>7, :T_STRING=>26950, :T_REGEXP=>189, :T_ARRAY=>10224, :T_HASH=>193, :T_STRUCT=>1, :T_BIGNUM=>5, :T_FILE=>7, :T_DATA=>1674, :T_MATCH=>22, :T_COMPLEX=>1, :T_NODE=>3468, :T_ICLASS=>37}

ObjectSpace is your friend; not sure about #2.
