Now that all current CPUs except for some low-end embedded ones are multi-core and fully programmable GPUs are ubiquitous, I don't think Plan 9/Amoeba-style SSI is really all that relevant for anything other than HPC. However, I do think distributed network-transparent sharing of devices and services along the lines of QNX or Domain/OS is more relevant than ever.
