Well I should read all the email first. the source code can be looked at by following the links from http://www.mobilewikiserver.com/1.4.html and getting the desktop version. No magic is involved, it's just an object fileout of the Pier root. There are some changes to the object file out logic to uses a buffered UTF8 stream and a few minor changes in the object to serialization logic for performance reasons. Thus the file out runs in 50% of the time that it normally would. No doubt using the Squeak buffered multi-byte stream change would achieve mostly the same thing. I'd like to convert this to image segments, as soon as someone figures out a rational subset of that missing all the etoy & project cruft.
