        Hi all,

  Sorry for jumping in the discussion so lately, I've been quite busy those
  last days.

I must say all this is really interesting. I unfortunately do not have
the time to investigate such things deeper, but i'm really interested in
a distributed layer. Had a very quick look at pyro, seems compact and
clean. If any of you experiment in this direction I'd like to hear from
the details, problems etc. As far as I can understand things, it seems
that Tom and John are speaking about similar things, if not the same.

  BTW about weakrefs and pickle, I can effectively confirm that weakrefs
  are used, mainly in objects (which hold a weakref to their EC) and in
  to-many faults (AccessArrayFaultHandler) which for technical reasons
  hold weakref of the object referencing them.

The other major problem will probably be that most operations, such as a
fetch(), are propagated through the object store hierarchy from an EC
down to the DatabaseContext(s), but at some point DBContext calls back
methods on the calling EC.


John: after a quick search I was not able to find any english-written
resources about papo and cimarron, is this available somewhere?
