In reply to tobyfk:
The Shihuh were certainly Omanis, but some of the people in the likes of Wadi Ghalilah, Wadi Qada'a and the Tawyain and Asimah areas of RAK emirate were certainly Emiratis (or Emmoroids as old Len Willis used to call them).
I'll digress here, cos it's a story worth telling -- you never know, some others who post or visit here may find it of interest.
Now Len was a character - a true Northumbrian -- he was in his 70's when I was over there. He was with Geoff Oliver on the FA of Ichabod on Scafell East Buttress in 1960, and hadn't climbed for years when we met up with him whilst he was out for a walk one day in Wadi Bih. Had some great days out with him, doing 'Jungle Book Wadi', and Jebel Qiwih by moonlight. His knees were a bit arthritic, but he still managed to follow me up the odd VS. I even managed to get his name on a FA in Wadi Bih in 2000 -- though it was only V Diff!
He married a lovely Lebanese lady, and had lived in Sharjah for many years. Sadly, Len suffered a stroke not long after I left, and my e-mail contact with him dried up, as did John Gregory's. I know one of his daughters took up a post at Sharjah University to be closer to him, but whether Len survived for any length of time, I do no know.
Len wrote an article on the UAE scene for the FRCC journal of 2000, and when I last saw him he showed me his almost completed and well illustrated book on Persian Carpets about which he was a bit of an expert.
