Very nice., I'd be interested in this.  Just to be sure: are we talking
about https://github.com/phillord/linked-buffer?

In that case I'd still need to buffers open for the same file, correct?
I'd just have them open permanently instead of creating a source buffer
when I want to edit source code?

I won't ;-) My back-log on the orgmode mailing list is 2000 messages
now.  That is also the time of my latest git-pull....
