Writing a daemon would also include developing or choosing an
appropriate protocol, which adds at least one more layer. To be honest,
I think it's unnecessary bloat for a router/firewall.

Even if I don't really like PHP myself, I'd say it's better to stay on
it, as it's also one feature that makes m0n0wall unique.

One possibilty would also be to write the deamon in plain C and then
spin of PHP processes for each request, but this would slow down the
whole process.

Especially with PHP 5's OO-features, it should be possible to abstract
things and then write specific classes.

The only Unix I really know good is Linux, so I can't really help here.
I've been using FreeBSD only to develop for m0n0wall, and even then, I
editted the files on Linux and built the m0n0wall images over NFS.

If we are going to some OO architecture, it should even be possible to
write the GUI independent of the underlaying operating system. This
mostly depends on a good architecture of the code.

I think that 64 MB are way enough for a router/firewall like m0n0wall in
normal environments. fli4l, a Linux based router I've been using for
more than three years, still runs with 16 MB of RAM. However, fli4l
doesn't have a web interface.
