In the meantime, I'd like some 9fans who may own a Sheevaplug,
possibly also other ARM equipment supported by Plan 9 - 9fans with
some interest in Go - to try to install Go on their devices.  The
instructions are detailed in "codereview" CL 7987044, see the Go
documentation on how to contribute for guidelines.  Briefly, the idea
is to clone the "tip" (default) Go development tree and build it
_after_ applying CL 7987044 as a patch.  To the best of my knowledge,
"make.rc" will build the Go distribution and "run.rc --no-rebuild"
will run the tests.

Ideally, I'm looking for a breakthrough with a pristine Plan 9
distribution.  This would require building the ARM (5?) development
toolchain, then the entirety of the runtime for the ARM as well as the
appropriate kernel(s).  I guess the interested parties already know
this, as well as how to boot the ARM equipment with the most recent
available ARM kernel.
