I wish they don't. That would take focus away from B4X, because running an environment like that isn't a setup-and-forget deal, it's something you need to work with continuously. The only way it might be acceptable, from a focus perspective, is if Anywhere Software would hire another person to handle it. As far as I can tell it's something that they are intensely uninterested in doing. Besides, the service would probably have to be somewhat expensive to cover the cost of that person, which wouldn't make it attractive for most members.
I wouldn't mind a detailed and easy-to-follow guide on how to do it on a standard VPS though. Come to think of it, perhaps Klaus could be persuaded to make a nice booklet about it? Or somebody else. I'm sure there are forum members that would even be willing to pay for such a document.
