Actually, we used it last year at the Durham Tech installfest and tried
to do some network installs through it.  It didn't fare so well; the
installs were pitifully slow, much slower than the 100MBit network on
both sides.  This wasn't really due to iptables though, but the
throughput limitations of the PCMCIA bus on that older laptop.
