This is correct. The idea is that any xPL app/device on the network should
be able to listen in to all other traffic.
E.g. a monitor, state cache, etc.

I agree with Tom here - I don't like the idea of configuring things like
broadcast address, listening IPs etc. via xPLHal.
To me they are core elements of an application, and as Tom says, they are
global to the machine.

First beta version available here:
http://www.xpl.myby.co.uk/downloads/utils/xplsettings.zip
(it's written in pure C++, so doesn't need .NET or anything to work)
It will ship as part of the next release of xPLHal Manager.
