So this is how Go will make its appearance on Chrome Browser & Chrome OS? Pretty cool. I was a little scared off from NaCl from the C/C++ requirement, but Go will make that a little easier to handle. When is 1.3 suppose to be released?
Around 7 months from now according to http://blog.golang.org/go12.
As http://golang.org/s/go13nacl describes, supporting Chrome is not a goal for 1.3 release, only being able to run nacl-sandboxed executables from command line.
