Arabic fonts on Mac

[RonLF06]

I'm putting together a bilingual book in English and Arabic. I'm using InDesign CS3 with a G5 running OS 10.5.6. Before splashing out on Arabic fonts I checked the Linotype support site. It warned:
"You need to use the Middle Eastern Version of InDesign for the correct representation of the script."
Am I seriously supposed to buy another complete InDesign version, for one job. Is there no way InDesign on a Mac can be made to run Arabic fonts, when InDesign on Windows can apparently handle them with no problem?

...essentially you will need the ME version to edit in the Adobe environment with any great accuracy...
