  In the OLPC Etoys image, not much.  The Croquet system (written in
the same Squeak) has better real time one, and there are a few other
attempts at other private companies.

  I don't know.

  There was an unsuccessful attempt to write MPEG4IP binding to
Squeak.  But that was done at wrong layer.  The right thing was to
implement SIP and other protocols in Squeak and use that kind of
library as codec optimization.

  In a "works-for-a-demo" way.

  It uses GSM codec.

  In a sense, yes.  One could run the Squeak image as a background
process.  The image could be a stripped-down Etoys image so that
unnecessary classes and methods can be discarded.
