Nesting? that’s very interesting, I always felt that emacs’ separation of 
data in “atomic” buffers, unnested, was limiting…  Couldn’t a such facility 
come with some semantics that could ease the working with multi-modes and 
multiple-formats files, such as php files (including html), html pages 
(including javascript and css), org-mode and its source blocks (currently 
opening another buffer to work), makefiles including a lot of shell-script 
programs, bison/yacc files including C, etc.?

PS: that makes me think of some other reaaaally handy feature that would 
be so convenient: the ability to *include* the content of a buffer inside 
some other buffer, so both’s data are connected, and you can see many small 
files’ content at once while working on some multi-semantics file… but maybe 
it’s a stupid/useless idea (it could be synchronized maybe? or be overly 
difficult, dunno u.u)
