Imeem uses Mono on their servers and also they use it on their MacOS port to reuse the same codebase that they had on Windows. Like iFolder, they are creating a native Objective-C interface using Cocoa and communicating with Mono to call into the engine.
My understanding is that Imeem uses Mono's cryptographic codebase extensively.
Someone should do an interview with Dalton Caldwell founder and CEO of Imeem.
