OK, there are other read-only distros too (the pfsense 'embedded' one  
is all but RO).   Technically,
if one could squeeze NanoBSD into 4-8MB, we could use the pfsense/ 
m0n0 XML-based config system,
and just keep the config file in a single (or small number) of flash  
sectors at the end of the device.

A similar configuration system that didn't require PHP would be even  
better.

Then we just need to (perhaps) re-implement/replace the linux "mtd"  
system, and a F(F)FS can wait a bit.

Indeed.

Is there any reason to not approach Intel about a bit of 'funding'  
for FreeBSD on Xscale?  They poured some cash on Wasabi
for a similar effort on NetBSD.
