Other examples are the INOC-DBA service which many
NANOG members use http://www.pch.net/inoc-dba/
And both SIPPhone http://www.sipphone.com and 
Free World Dialup http://www.pulver.com/fwd/ have
been operating in a similar way for a couple of 
years. These last two are now expanding by also
offering PSTN connectivity, but they are rooted
in a non-PSTN VoIP service.

Many groups are setting up their own similar
systems based on the ready availability of 
SIP compatible phones and PBX software like
Asterisk http://www.asterisk.org. The Internet
is fundamentally a network of IP routers. The 
PSTN is fundamentally a network of voice switches.
A PBX is a small voice switch. Asterisk is software
that provides PBX functionality on a UNIX PC therefore
using Asterisk and the Internet, anyone can build their
own network of voice switches for whatever purpose they
want.

I'm surprised there are not more smaller PC's 
offering this as some kind of an add-on service.
Once you have a sizeable customer base using 
always-on broadband, why not help your customers
set up always-on voice services. Of course in the 
absence of such support from ISPs, there is a vacuum
which Skype is attempting to fill using non-standard
software.
