Hi,

Giovanni asked me to contact the DeltaStreams team. I just wanted to
inform you that I wrote some documentation about MC2:
http://wiki.squeak.org/squeak/5624.

MC2 is able to manage ChangeSets as well as PackageInfo. So, I'm
unsure if DeltaStreams are really useful. I also published some notes
on the Summer of Squeak blog.

Ask me questions if you want.
