Hello, I saw this and the blog post about it just now. This is very interesting! I have started working on this on my own, in the hope of eventually sharing something useful. However, I am a guile (and guix) novice and I don't have plenty of time and my job is completely unrelated to computers. That is/was a mean for me to learn more about guix and guile, by the way. I thought that because it was in the roadmap in low priority I could take my time. Anyway I am glad someone is working on this. What I have done so far is probably not useful at all because it's not much, very far from complete and probably a lot messy. Whatever, if I could help in any way please tell. Do you work on a specific branch or some external repository? Do you plan to work with others at some point or do you want to want rough it on your own for now?
I look forward to hearing from you. Thanks!
