I received an unsolicited request to sign up for one called [url=gulfdotcoms.com/]G-com[/url] recently. It looks pretty new, and there's no search function, but it's supposedly focused on the Gulf region.
This might help you to locate Saudi Arabian directories: [db.alba36.com...]
As to splitting down the Asian forum, I am sure that will happen, but it will probably be in a year or two. At this time, there simply aren't enough members from Asia to maintain meaningful discussions in separate fora. Woz - who is sound asleep right now - is preparing some great overviews over his vast realm and they will be split up in much the way you suggest. We can expect them soon - it is a massive piece of research he is doing.
PS. Skirril: Did you ever find the Switzerland discussion you asked about some time back? It is right here [webmasterworld.com].
