Go is a clean, intuitive language with a very robust supporting ecosystem and a strong concurrency model. It builds fast, small code and makes quick work of big problems. Why shouldn't there be a big following of one of the better platforms to come out in a long time?
The runtime kind of makes it a silo; ie: hard to bind other languages to it through an FFI.
Of course if I am mistaken or there's something being done to address such a scenario then I will be much happier seeing more and more infrastructure code shipping in Go.
It's not. It's a new Java, not a new C++.

More or less impossible: GC and goroutines are not optional so you'd need to cleanly setup and shutdown the Go runtime. You'd have to embed Go as you do Lua or Python.

Not according to the Go developers. "Go is a general-purpose language designed with systems programming in mind." http://golang.org/ref/spec#Introduction
Go has absurdly simple FFI through, as mratzloff mentioned, C. This is self-promotion and apologies, but see my submission history for two examples.
