The idea isn't to get Squeak to serve out the filesystem, but to have a way to use the FTP protocol as an interface to any data you want, in the same way that dynamic web servers let you use HTTP for applications far beyond serving static HTML files. Well, Ian Prince wrote a couple of weeks ago that he and Lukas Renggli had started to tackle it at Camp Smalltalk in Brussels. Since then, Lukas has been hacking away, and he just let me know that he had support for passive clients done...

Lukas says he's already working on an FTP view for SmallWiki2, turning BBEdit into a dedicated wiki editor.
