   Any suggestions/pointers/flames/etc?

Oh boy. I've once done this for someone, but I can't find the
macro. And I dont' want to spend half an hour reconstructing
it. Anyway: the trick is (or at least one trick is) to
recursively analyse the \vtop that you make for the address,
	"\def\address#1{\box\addressbox\vtop{#1\par\apart}}
	"\def\apart{\unskip\unpenalty\setbox\linebox\lastbox{\apart}}"
measure the length of the first line
	"\box0\hbox{\unhbox\linebox}\global\linelength\wd0"
and then \wd\addressbox\linelength".

Something along those lines. (Get more ideas from 5.9.6 of
TeX by Topic, or Tugboat 11(1) 51--53.)
