Sure, but it depends on what you need to do. From my perspective Mirage is OCaml's 'killer app' (I'm sure others would disagree). Where I could see it excelling is as an open-source home server platform. I'm not sure what the current progress is but I know some of the Mirage developers were working on this particular use case, I'll see if I can find the link. Could something like Mirage exist for F#? It could, though the Mirage team have a considerable head start. EDIT: The project I was referring to before is Nymote: http://nymote.org/ http://nymote.org/
