Hello Dave,
There is already a domain company in the Middle East where you can register real Arabic written domain names and not IDN, even the TLDs are written in Arabic. As for IDN, I don't know if there are people who are interested in this or not. By the way I have banking.net (IDN).
fritalover, teslam 7abeebe. But I still think this domain can get a fortune especially that there is a new Games Firm that has been opened recently and it's producing professional and amazing 3d games and it already launched it's first game which looks like "prince of persia" game and it has the option to run in Arabic, English or French language
Regards
