I believe AppScale supports Go, so I don't see how it's any harder to port a Go App Engine app to run elsewhere than porting Python or Java apps. Go to Google is not like C# is to MS. Microsoft's C# platform is not free and they have complete control over the language. The Go compilers and libraries are open source. You're free to take and use them as you see fit (under the terms of its BSD license). Google can't "lock you in" to using Go.
