your version is nicer to the eye ;)

There is something i don't understand though. I can arrive up to
PositionableStream class>> on:
---------------
on: arg1
     ^ self basicNew on: arg1.
---------------
After that, I can't find where "basicNew on:" is implemented.

Actually the JSON strings I send/receive can be a bit large. Because 
they represent objets with inside
packed quite a bit of information e.g. pictures. I would say never 
larger then 1 MByte, if possible.

Still at the moment I will not worry about efficiency. I am trying to 
convert a Ruby+Mongo
server side of an app into Cuis. I have time till end of the month to 
make it work.

For the moment I am going to replicate the database as a list of objects 
in memory,
I will consider persistency better in a second step ;)

Bye
Nicola
