You could port as much as what was already on Plan 9, so same restrictions apply as UNIX to Plan 9.

The C compiler is there, the same way as in Plan 9, Inferno is the evolution of Plan 9, in one way it was Bell Labs response to Java, in other way it was another take to what went wrong in Plan 9 like the failure to design Alef to be usable.

Naturally Limbo was prefered as the main userspace language, from safety and usability point of view.

Ah, okay, I thought limbo was the only userspace language, which would massively hinder adoption. If that's not the case then I know of no particular technical reason inferno wouldn't be a good option. I do wonder if other people had the same misunderstanding as I did.

Here is one of the places where you can see the reference to C compiler being available.
