Also, I have seen some recent commits from emacs developers to guile. So the two projects are talking to each other.
Now, imho, the success if emacs-guile strongly depends on whether they manage to share the load across several developers. A more open development culture surely would help.
Emacs-guile is working today. That's a first after many many years of talk and proof-of-concept stage efforts.
I hope the development will pick up speed once guile 2.2 and emacs 25.1 are out. Both projects underwent some big changes/improvements lately.
One sign of live is that bpt's improvements to guile elisp were rebased on a recentish guile-master. This branch lives in the main repository now.
