Almost no chance, because "mainstream" would require a huge amount of software to be written or ported for the operating system that does not currently exist. When it comes to things like multimedia and games and webbrowsers and standard office-suites that account for the vast majority of the average person's software use, Plan 9 is not an option. It is true that 9front has support for running virtual machines now, but I see little reason that the average person would ever choose to be running LibreOffice in a virtual machine inside Plan 9 as their standard way of working.

Oh, is it a desktop-only OS? No embedded device / server capabilities? These two worked out for Linux...

Its sucessor, Inferno, has been bougth by Vita Nuova and they target it at embedded devices.

Very interesting, thanks. From the descriptions, the architecture looks kickass. Looks like an ultimate device driver toolkit.

No it's both a server and a desktop OS. The architecture semi-requires the ability to be both cooked in. In my usecase I have my terminals which are desktops that boot off of my main fileserver.
