This is a bit late but I've been extremely busy the past couple of weeks. On the 20th of May 2009 ArabTechies organized a code sprint for 3 days to solve problems related to processing Arabic. I, among other software developers from Arabtechies, worked for 3 days on several projects. I mainly worked on integrating the features of the Ar-php library into Drupal 6. You can find the resulting module on this project page on drupal.org.
Other than that, the code sprint resulted in some pretty cool tools and libraries. All of them can be found on the code sprint releases page here.

What about transforming that
What about transforming that in a series of core patches, so that Drupal 7 can be an even greater release?
Not the right place
I'm not sure if you mean ar-php or all the releases of the code sprint but either ways, Drupal's core is not the right place to include this kind of functionality. Those are all Arabic related issues which should be grouped into modules not added to the core Drupal.
