Networking
Version 2.0 of Squeak supports sockets. If you are on a web-connected network, you might want to try...
HTTPSocket httpShowGif: 'http://cal-parks.ca.gov/images/sun.GIF'.
There are many more examples in the Socket class.
Also included with this release is a complete WikiWiki server. See the accompanying information on WikiWiki.
Squeak's FileList has also been extended with network access. This feature is newly added, and will probably require a little shaking down and tuning.
