The page table needs to be implemented in such a way that no two processes' virtual memory pages are mapped to the same physical page.

While this solution protects processes, it may also impose limitations on processes. If the "viable" part is about real-life OS, then it's not - most modern operating systems will allow certain pages in some processes' virtual address space be mapped to the same physical page. One good example is memory-mapped IO spaces.
