I was such an OS/2 fanboy in the early/mid 90s, that this idea is immensely appealing to me. Unfortunately, my recent efforts at getting OS/2 running under qemu-kvm/libvirt have been not very successful (mainly can't get a working combination of ethernet driver and emulated card), so this would have to be pretty back burner for me.

EDIT: this was supposed to be a reply to a post saying someone should make a Mastodon client for OS/2 and call it OS/Toot, but I hit the wrong key in mastodon.el.
