The ThinLinc Architecture image in "Chapter 2. ThinLinc Architecture" is very much outdated. It hints about MacOS server support, which we no longer push. It also lists clients which are no longer available: Solaris, Irix, Neoware, SunRay, TLCOS, Java Browser Client, X terminal.
A few examples designs was worked on and we have decided to go with a version. I have also looked into different "diagram tools" to make a diagrams look a bit nicer then what dia can produce. Tried inkscape (too much work) and some online tools. Found a tool name draw which is very nice and is a open source (GPLv3) HTML5 diagram tool . Where content produced with the tool and all available cliparts are free to use for any purpose.
Looks nice. Updated text for more clarity about supported devices.
