In past I have posted some tutorials and flash codes to import arabic in flash using xml and css and also about Flaraby.

Now you can download Flaraby AS3 as an Adobe Flex and Adobe Air component (SWC) that enables rendering Arabic, Persian or Urdu text together with Latin (eg. English, French, Spanish or Italian) text in SWF files at runtime.

You can download FlarabySWF from Adobe AIR Marketplace

You can read in detail about Flaraby3 here and can also see some examples here.

Read about old version of Flaraby here.
