What kind of size range are you targeting?  I'm trying to remember what I
had my cheapo script down to; I think I had it workable on a 64MB flash card,
but I'm lazy.  Currently, I'm just doing whole systems on 256MB cards.  Since
I'm doing small numbers, well, the cost of a 256MB SanDisk card ($30-40 mail
order) vs. the cost of time spent trying to shrink the system...

Ooh.  The crunch stuff seems a good match, at least for rarely-used binaries.

Well... Putting on my freelance writer hat, I wonder if I can sell someone
on an article series about doing it.  If I can, then I can probably justify
putting real time into it.  Hmm.
