     You can run, in one Smalltalk system, an IDE that operates upon
the
objects of another Smalltalk system which is headless. This is what I
do
in the Spoon project[1]. For that matter, the IDE could be implemented
in Emacs or whatever.

     Yes, and you don't even need to have the compiler present in the
target system; you can install compiled methods directly from a remote
IDE system. Spoon does this as well.

     The fundamental objects you need for a running system are few in
number. A minimal Smalltalk image is very small. Given such a minimal
system and means of organizing the system into modules, you can just
use
image snapshots as your fundamental storage unit, use live
communicating
objects, and dispense with all other file formats.
