Well, the technique I gave works for JDEE which works for both emacs. It
should all work. Where it's going to fail is if the various files don't
have all their requires sorted -- at the moment if you are always loading them
in the same order (with ess-site) then there is a good chance that they are
not. 

Another possible solution would be to make a file called "ess-autoload" as
below. Then remove the equivalent form auto-mode-alist from ess-site and
replace it with (require 'ess-autoload). Then people running can 

(require 'ess-autoload) 

and it will autoload the first time they open a file, or 

(load-library "ess-site")

and it will work as now. 

Of course, you might need some more commands autoloaded -- I don't know how
many different ways people come into ess. If it's a lot, then clearly this is
a pain in the ass to maintain. 

Anyway, this is just a suggestion. I can understand why you might not be keen
to go through the work, and I am a very minor user of ESS -- blame it all on
Stephen Eglen, it's his fault I am doing this. 

Cheers
