Ted Shelton done a brief analysis of the economics of starting a VOIP telco and conclude it will take only $8,000. (Via Kevin Werbach)
I made a similar rant last year arguing that people will wonder why they dont do it themselves once they discover how cheap it is.
I also believe that IP Telephony will take the same path as Email since it has similar cost basis. ie. some will setup their own server, some will run inhouse, some will outsource and the mass will subscribe to a service, e.g. hotmail.
