I'm not so sure; someone cuts an ISDN-30 into our building and the sky 
falls down.  Someone cuts some fibre carrying IP and life (and

Perhaps you've made a fair and good comment on the marurity of most

mind, is that VoIP across the internet, when done well, imports all of 
the opportunities of internet routing into voice service.
