Right :). For MIPS especially..., kernel for Agenda is 2MB uncompressed.
So, basically multiply by 1 and a half normally. (Though it's not as bad
because kernel is non-PIC) Helio and Agenda hardware wise are pretty
similar, though Agendas got tons more flash, but the Toshiba processor in the
Helio is a little higher horsepower. (Faster, but the VR4181 is a bit more
advanced in other areas... like this one that affects code size, VR4181s'
pipeline is smart enough to stall if you load register and use it next cycle,
where as with Toshiba the results are undefined)

Yes..., I could definetly do the port. I'm ironing out ARM and uClibc, but
as time allows I might be doing some uClibc work with MIPS. Fundamentally I
have a love hate relationship with MIPS though..., so damn simple, but such a
pain in the butt when I look at those file sizes. *sigh* Anyway, it's on my
"long todo list" as well as creating a replacement for libstdc++ for embedded
enviros. Though admittedly getting uClibc working for MIPS is higher up on
the list :-).
Anyway, the unix domain socket thing is a good idea, but if you want to make
Micahs life easy, you could change WANT_IN to UNIX_DOMAIN or something like
that, and stick it into the configuration.
Thanks,
