Can anyone confirm if this allows linking native libraries? From the looks of the "compiler", it seems it might be hacked to produce a binary statically linked against, say, SpiderMonkey.

Beyond coolness, it seems a waste of effort to tailor this release to Go, when similar effort might have been expended, e.g. to define a simple protocol talked over a UNIX fd that any static x86 binary could implement to integrate with App Engine.

There's a lot more than sandboxing to rolling a good App Engine SDK. A large amount of effort went into designing nice, idiomatic Go APIs for accessing the App Engine services.

It looks like the answer is no. You upload your Go source code and App Engine compiles and runs it; you don't upload binaries.
