Guile emacs thread (again)

Hello!  It's been a while since the topic has come up on this list, but
many of us are interested in it, and maybe some developers don't know,
and I hadn't seen any conversations on the list despite recent progress.

Anyway, it seems that BT Templeton's emacs on guile project this summer
has gone fairly well, and it looks like almost everything runs.  See:
  http://www.emacswiki.org/emacs/GuileEmacs

I remember reading Andy Wingo's email about this a few years ago,
"guile and emacs and elisp, oh my!":
  https://lists.gnu.org/archive/html/emacs-devel/2010-04/ms...

I found it very inspiring.  It seems those things are fairly close.

So this email is partly a:
 - What now?  What's the chance of work towards guilemacs moving over to
   an official emacs git branch, and that port happening, anytime soon?
 - Is anyone running it?  How's it going for you?

(I'm mid-compile of the guile wip branch right now...!)
