Well, there is always the Bloody Bay Dive Resort (coming soon)! (Yes, Chip McCoy's sign is still up on the front if the old lot where Chris McCoy and ex-wife Laura used to live, even though the McCoy's sold that property long ago.)
But in answer to your question, nobody I know takes people out on the north side. Even if I had a work permit to do it, I would want to do DLD's from shore. There's just too much chance of people getting trashed on the fringing reef. Personally, I do all my dives from shore over there and haven't gone out on one of the boats in many years. The only site I can't reach is Cascades, and that's just because I'm too lazy to swim all the way out there.
I once grilled Perry McLaughlin about why they didn't develop Little Cayman for shore diving the way Bonaire has been developed the last few years, and his answer was that all of the shore entries were through private property. I guess he is right, though I do think there's a little strip down by the entry for Cumber's Caves which is public land.
