In what way?
I looked at http://www.milkfish.org/ and all I see is a "conventional"
VoIP router. It may have a FXS port or two (to connect a local analog
phones) or an FXO port (to connect as a modem to the PSTN) but nothing
there about networking over phone lines.

I still don't see the value of this approach. Considering the cable
usually installed by the PTT (CAT2 I believe), one would expect a max
distance between stations of a couple of km and a max transmitted rate of
at best several Mb. Also you can't merely "splice" the customers' cables
together; one would likely have to install some sort of analog
bidirectional bridge. It seems that any of the 802.11 approaches are
superior in all respects.

Yes it is possible, theres various devices on the market todo it.
There is one big catch, you only usually get 10 meg links. Also the
devices are hard to find, I know the one I got (which I am not using
because it didn't work in the UK!), is 10 meg, but links to the
computer via USB.

What's wrong with USB? USB performs as good as 100Mbit Ethernet, generally.
Anyway, people have been using DSL technologies on phone wires for quite
some time.

USB is a shared bus. Worse, the bus speed slows down to match that
of the device on the bus. It should be used for nothing more than
mice, keyboards, and still cameras.

1.1MBit thinnet more like it.

Speaking from experience, it's not the ideal solution even in that case, to be
sure. You pay way more for less bandwidth given available alternatives.
