I'm in. Where do I put the money?

I would also be willing to donate although the project would not be very viable. It's a lot of work, Common Lisp is not a currently fashionable language like Rust, it would not have support from RMS.

It would probably die out soon. XEmacs is one of the longest living Emacs forks and even that is dead(ish).

Still, I'd put up some money for this.

>it would not have support from RMS.

Is this something we care about? RMS doesn't own lisp-based text editors.

I don't care but many follow him[1] which might take a big bite out of your potential userbase.

[1] Not without reason since his foresight has been correct wrt privacy, civil rights, etc.

I would work on it for money. My company's website is listed on my HN profile--there is contact info on the website.
