Rhiostoma & other operculate land snails?

[radular]

In was surfing around earlier today when I came across a thread on another snail forum about someone keeping Rhiostoma snails. I was shocked by this because I have never heard of anyone raising terrestrial prosobranchs (also called "operculate" land snails, besides being snails, they are unrelated to other terrestrial slugs and snails & reflect a second invasion of land by mollusks.)
Here's the forum thread, with photos.
This discovery resulted from trying to look up the differences between Neohelix and Mesodon & I wound up stumbling on the Jacksonville Shell Collection. This is the page I found......and here's the photos that caught my attention. As a result, I had to look up what the animal looked like which wielded this strange shell. That;s how I found the "Super Snail" site.
So what I want to know is have any of you heard more about these or other operculate snails snails? How well do they take to captivity? I understand Rhinostoma smithi Southeast Asian in origin (Thailand and Malaysia), so I wonder how one goes about acquiring such animals (hypothetically, as I have no means nor real motivation to do anything international)? Has anyone even bred them in captivity before?

I've seen them for sale now and then but never heard of anyone successfully breeding them. Ness (who has them in that post) does not have them anymore but sadly has cut back on snail keeping. I don't believe she ever managed to successfully breed them.

Those are possibly the strangest snails I've ever seen. If I ever see any for sale, I'll give them a go. They obviously breed, the only problem is figuring out how to encourage them to breed in a box.

There's quite a lot of info on them if you do a search for rhiostoma on the supersnails forum. Someone seemed to suggest that one of the problems was ensuring you had both sexes (similar to the megalobulimus problems). As well as differing opinions on diet

Awww... well that's a shame. They're beautifully shaped animals. I hope people continue to do more work with them and try to find out how to propagate these animals in captivity.

Wow! I can recall seeing shells like these before, but I never knew what they were!
