That's how my version currently works. Unfortunately, mine likely
wouldn't be much good to you because there is a massive amount of
overhead that I added to fine-tune process controls - and I can't
merge into my github repository to demonstrate until the daily
mercurial mirror updates. Of course, your idea is actually as simple
as using popen, the non-standard function fileno, and dup2 to replace
stdin if you wanted to minimize the amount of code you touch, ie.
(somewhere in main()):

FILE *dwmhelper;
if(argc == 2) {
 dwmhelper = popen(argv[1], "r");
 if(f) dup2(fileno(dwmhelper), STDIN_FILENO);

Actually, I'm unsure that dwm didn't actually work this way by default
at one point. I seem to recall finding it somewhere in the source in
some long-lost revision once when I went repository-diving.
