I'm having trouble fitting everythign in a 1.5MB floppy image (600k 
kernels don't help here...), and SSH (even a stripped down one) is 
putting me over by about 100k.  I can go for 4MB and that *should* give 
me sufficient space to do whatever I need (including the tinyX server) 
if I stick with uClibc.  However, if I can go up to 32MB space (I can 
compress this if I have to in order to get it down to size, but that 
shouldn't be a problem, they do this on 16MB iPaqs after all :), I can 
easily get glibc on there, eliminating the need to carefully go about 
choosing apps that are compatibile with the stripped down libc.  I 
wouldn't even have to use busybox then as space wouldn't be nearly a 
concern (did you know busybox statically linked to uclibc can fit a 
mostly functional linux system into under 600k?).

I'm also making some "demo disks" that do the NFS root fs and tftp 
loading an image into a ramdisk that are coming along nicely.
