These are just some idle questions.
Is the source from Hemlock at all useful as far as editing functions for porting over to a proper Carbon based application for an Aqua compliant IDE?
Are there any other independent projects besides Clotho in this area?
Is the goal of this list to work on an implementation portable IDE (OpenMCL, SBCL, etc), or is a particular implementation favored?
What about integration with Interface Builder?
This is a very quiet list. Could it be that many people think Emacs + SLIME (or some other non-Aqua solution) is "good enough" for now?
SLIME has done some clever stuff to support a wide variety of Lisp implementations. The techniques used in that project may be applicable for a portable implementation. How much extra work is that compared to just supporting a single implementation?
Is there a current wish list / spec for this project?
