Looks like there's a huge difference between small Linux and something like Contiki. Any time you run out of on-chip SRAM without an MMU (e.g. anything really low power) Linux is not a good fit. That non-Linux space is gigantic and there's room for something like Contiki as well as much lighter systems that have some form of non-IP networking. We evaluated a bunch of small kernels (ended up with uc/OS) but there are dozens of open and proprietary kernels that fit specific needs both larger and smaller than Contiki that are non-Linux for good reasons.
