For the record,
If it wasn’t for the developmental versions, FOG wouldn’t work in my environment at all.
And, from what I’ve seen, it’s really stable.
Tom primarily focuses on the imaging features in FOG (who would have guessed??) and makes sure that it works for all sorts of hardware. This is understandable, because he is only one man, and fog has a lot of razzle dazzle plugins and other features that aren’t specific to Imaging -> Naming -> Joining to domain
And, of course, all I do with fog is: Image -> Name -> Join to domain… and FOG is really good at that.
