So I kind of was a bit angry when I stumbled upon this and I really didn't think you should take the time to loop up a provider. According to their support wiki they didn't have 4.0.
I solved the problem by going manual and writing a site with the features I need as I stumble upon them, awaiting your "medium trust" supporting release.
The thing that bothers me with your FAQ says: "Orchard is tailored for today’s shared hosting environments, where users potentially have less control over what software is running on the server."
Waiting for your release since I think the product looks really promising.
