Multics resurrected: Proto-Unix now runs on Raspberry Pi or x86

"Does Multics have any useful features that are not present in modern OSes ?"

Its virtual memory implementation comes to mind: in Multics, "files" were really persistent memory segments, i.e. all files were "memory-mapped" in Unix-parlance.

The concept was not without problems of its own (see the linked article above and the articles linked therein); but given today's availablity of reasonably fast, persistent mass memory technologies I think that exploring direct mass memory access while doing away with traditional file I/O might well be worth exploring once more.
