Am i wrong? Any work in this direction would be great. It would help me move emacs-framebuffer forward. I use w3mimgdisplay there which works on the Linux console. w3mimgdisplay uses quite similar protocol and also caches the images for faster redrawing. There was discussion about some aspects, for example: id:87zh9hrxfj.fsf@logand.com id:87czzu7y5r.fsf@logand.com id:87mtyw9c7f.fsf@logand.com Unfortunatelly, I think it would require quite a lot of changes to the C code.
