Hi Ale,

  Can you talk a little bit about the architectural differences between DNG
and Squeak (or other Smalltalks)? It will include advances developed in the
area of autonomic systems or structured overlay networks? something like the
Erlang's supervisor tree or subsumption architecture?
Best regards,

Hernán
