I happened to have quoted part of that article that now seems to have vanished from the net:
The technology that allows automatic context analysis - that makes an isolate 'b' turn into an initial b when you add another character to it - is linked to the font, and can in OS X be of two different types: One is Apple's own which is called AAT, for 'Apple Advanced Technology'. The other is the one mentioned above, called OpenType. (*) A program will have to support either one or the other, and a font is normally also either one or the other. Apple started, as mentioned, to support OpenType font files from OS X, but it used its own AAT technology for Arabic context analysis. That is why Apple's own TextEdit and all programs that base their Arabic text handling on the OS X default, will use AAT. This includes the Arabic-aware Nisus Express, as well as all the programs that do not care especially for Arabic although they support it.
In these programs, OpenType fonts will appear in the font list and the Arabic characters will be displayed, but only as isolate forms: the program does not understand the OpenType indication of how to combine them.

This, incidentally, is why Safari suddenly stops displaying Arabic properly when you install Microsoft Office 2004: That also installs versions of Arial and Times New Roman that contains Arabic characters, but in OpenType format (as in Windows). Web pages will routinely ask for Times New Roman even for Arabic text, and as it exists on your machine and contains Arabic characters, Safari will go ahead and display those. But because this (Microsoft) font is based on OpenType, the Arabic letters it contains do not combine into words. You must dump the Microsoft version of these two fonts, and replace them with the older, Apple, version of the same fonts, which did not have any Arabic. Safari will then pick another, working, Arabic font to display the text of the website. -- Firefox, which supports OpenType ligatures, and other browsers do not have this issue.

(*) To be obnoxiously precise, the two formats differ in that AAT bases its context analysis (how letters combine) on commands inside each font; while OpenType fonts are actually simpler, as they largely refer to a common system resource called Uniscribe (a Microsoft product). It is this Uniscribe resource that does not yet, in its Mac version, contain the resources required for Arabic, whether that is Apple's or Microsoft's fault. Once a system version appears where this is in place, all existing OpenType fonts should start working properly.
