latency isnt as big of a problem as people pretend it is.  Jitter and
packet loss are the real killers.

Do the math of a TDM circuit from los angeles to london, new delhi or
any of the other places that it works.  TDM does have latency but it
doesnt have jitter and loss on the same order that IP networks do.  

For the people that want to correct me TDM does have jitter, for example
when a sonet link switches over due to a sewer contractor going crazy
with a backhoe.  It is just not that common, which is the point I made
above.
