athena evolution path to 3G networks 'not so reliable' connections

Hi all

Being a long term user of nevow/athena and quite happy with it I have a 
question which comes from the area of more and more clients being mobile 
  and thus not having all to reliable TCP connections on 3G networks. 
For all the stuff athena does it relies on a persistent TCP connection. 
The moment the client is disconnected the whole life situation is gone, 
everything is teared down and starts anew when the client reconnects.

Does anybody see an evolution path for athena moving towards being able 
to do reliable delivery and withstanding short (<20 sec) disconnects of 
the persistent connection?

 From what I see on Comet Daily there is an extension to the Bayeux 
implementation by dojo which seems to do exactly what I ask for.

I am not at all inclined to throw away what I have in terms of trusted 
twisted/nevow and head over to dojo/jetty but being pressed by an 
increasing user base on mobiles I have to think about the problems 
stemming from those mobile users and hopefully find a solution based on 
twisted/nevow.

TIA, Werner
