My last experience w/ busybox was >1 year ago and I'm not sure I was
using anything close to up to date, but...it was utterly linux-specific.
Given what it does and what I saw in the code I'd be more inclined to
write one from scratch. But having said that I'm not really sure it's
worthwhile; I think I'd rather put effort into putting some of the
existing tools on a diet (possibly under #ifdefs) and then use
crunchgen. I'm pretty sure you'd come up with something higher quality
and with a similar footprint.

Not sure about scripting languages but what's really needed is a
lightweight http solution that supports ssl. This can go a long way
before you get to php et. al. My last project of this sort used
tinyhttp (I think, whichever one Jeff Pozkanzer did) and php. But we
didn't try to fit in flash, we used compact flash parts. I think
tinyhttpd+php is also what m0n0wall and pfsense use but haven't looked
in a while.
