Live Distributed Objets - Why not in Smalltalk ?

> Hi people  (crosspost pharo and research)

> Quote from wikipedia (as you can see Smalltalk inspired them ;) :
> "Originally, the term was used to refer to the types of dynamic,
> interactive Web content that is not hosted on servers in data centers,
> but rather stored on the end-user's client computers, and internally
> powered by instances of reliable multicast protocols. The word live
> expressed the fact that the displayed information is dynamic,
> interactive, and represents current, fresh, live content that reflects
> recent updates made by the users (as opposed to static, read-only, and
> archival content that has been pre-assembled). The word distributed
> expressed the fact that the information is not hosted, stored at a
> server in a data center, but rather, it is replicated among the
> end-user computers, and updated in a peer-to-peer fashion through a
> stream of multicast messages that may be produced directly by the
> end-users consuming the content; a more comprehensive discussion of
> the live object concept in the context of Web development can be found
> in Krzysztof Ostrowski's Ph.D. dissertation[3].

> The more general definition presented above has been first proposed in
> 2008, in a paper published at the ECOOP conference[8]. The extension
> of the term has been motivated by the need to model live objects as
> compositions of other objects; in this sense, the concept has been
> inspired by ***Smalltalk***, which pioneered the uniform perspective
> that everything is an object, and Jini, which pioneered the idea that
> services are objects. When applied to live distributed objects, the
> perspective dictates that their constituent parts, which includes
> instances of distributed multi-party protocols used internally to
> replicate state, should also be modeled as live distributed objects.
> The need for uniformity implies that the definition of a live
> distributed object must unify concepts such as live Web content,
> message streams, and instances of distributed multi-party protocols."
