RE: xAP - The Proposed Architecture Explained...

[Stuart Poulton <swp@xxxxxxx>]

Jason,

Buy using a central PC you're creating a master-slave system, the
suggested use of broadcast messages makes the system effectively master
less for nornal day to day running. Thus other than the physical
transport, failure of a single device would not stop the whole system
continuing to function.

Regards


Stuart
