I know Martin's already pointed out the Jungerl, so just a few extra
notes:

My web stuff was just dead because of a recent server crash. Now I've
moved it from www.bluetail.com to fresh.homeunix.net. (Anyone know an
easy way to configure apache on www.bluetail.com to do a redirect?)

You can now download a daily snapshot of the Jungerl contents at
http://fresh.homeunix.net/~luke/misc/erlang/jungerl-snapshot.tar.gz
(I'm surprised Sourceforge don't seem to have this builtin.)

The 'psocket' program in Jungerl is similar to tuntap. It uses a
PF_PACKET socket to read/write to existing network devices and it can
be slightly easier to setup for some uses. It includes a small
ethernet hub as an example program (hub.erl).

Toodlepip,
Luke
