Well, its been a long time since I've worked at the level unexec 
operates at, and even then it was on System/360 and Series/1, but it 
looks like an interesting problem.

At first glance I imagine dealing with late-binding in Objective C is 
one of the challenges in dumping on GNUstep platforms?

Anyway, at the moment I'm more interested in getting the GNUstep 
Emacs.app working a bit better, so I'm trying to get my mind around 
the multi-tty stuff.

I've found  http://lorentey.hu/project/emacs.html.hu very useful in 
getting started on that.

Thanks for all the useful responses, everybody.
