I know that is possible, because MIPS devices have the same issues as an ARM one. As this fact, that SyncApp has been ported to ARM, rebuild it for MIPS-Linux will be easilly. Of course, we must to know, that MIPS architecture (such as an ARM) has two different models of CPU: with and without memory manager. Sometimes we can install ucLinux only, and in this case software must have a special build for it. May be it will be a two different versions for different kernels.
