     One of the biggest hurdles in bringing Ethernet to mobile/cellular
   apps
     has been its lack of synchronous capabilities. This is now being
     overcome
     in a variety of ways, both IETF-instigated and at IEEE, and through
     some
     proprietary solutions where vendors are re-introducing system
   clocking.
     See
     my footer note <fac:> that addresses this subject at the bottom of
     [1]this message.

     Speaking of which, what is the state of voip-over-cellular as
     essentially the
     last holdout of TDM? Will the new 4G stuff be able to support
     latencies, etc?
     Has the work on handovers-over-IP matured enough that it's viable?
