(Lights blue touch paper...)
So maybe it's time we started seriously thinking about a two-tier system 
based on different serializations of the VOEvent data model. The 
ultrafast layer uses a JSON representation of a VOEvent and TCP/V as the 
transport protocol; the normal layer uses the standard XML 
representation and the suite of protocols that we currently support.
(and retires)

    Cheers,
