Had a quick look at XOmB and XOmB Bare Metal. It sounds very interesting, but also very young. I don't even think they have a filesystem or moderately complex C application working yet.
I wonder how it performs compared to other C based OSes ?? Probably hard to compare as it is not a traditional micro-kernel. I believe that eCos is written in C++ (or a restricted subset), and I presume that it performs quite well, so given that, I see no reason why a D based OS/RTOS could not perform as well as eCos or other OSes. -- Brendan.
