You are right, this is mainly for one-time installations and such.

The cleanest way (in my opinion) to do this is exactly the way that I
did with the online pxeboot environment (there are other ways (like
loop-mounting the whole ISO or using memdisk), but they all download
more and use more memory).

1) Extract the ISO with

  bsdtar -x --exclude=arch/boot/syslinux --exclude memtest* --exclude
pkglist.* -f archlinux-2012.10.06-dual.iso arch/

This will result in a directory structure exactly like this:
ftp://ftp.archlinux.org/iso/2012.10.06/arch/

Put this on an http server.

2)

Use a gPXE or iPXE-extended pxelinux version, like gpxelinux, or a
custom version built from pxelinux and iPXE (for example, you can
include native ethernet drivers to speed up the early download). You
need this so you can use http downloads from the bootloader (you could
put the kernel and initramfs on TFTP instead, but you need HTTP for the
later stage anyway, so why bother).

3)

Add the following to your pxelinux configuration:

LABEL arch_x86_64
TEXT HELP
Boot Arch Linux (x86_64) live medium.
ENDTEXT
MENU LABEL Arch Linux x86_64
LINUX http://servername/arch/boot/x86_64/vmlinuz
INITRD http://servername/arch/boot/x86_64/archiso.img
APPEND archiso_http_srv=http://servername/ archisobasedir=arch
checksum=y ip=dhcp

(Similar for i686)

This will download the kernel from http and boot it, download the
squashfs images into memory (about 200MB total) and boot the live system.

I guess this will do what you are looking for.
