Re: Context parameters within Message Bodies

OK - I should have explained better :-)

I can see a situation where the logic is actually interpreted in
something like an ethernet<->serial xAP bridge.

On the serial side, we have PIC devices which are basic input /
output type telemetry modules.

On the ethernet side we have more sophisticated stuff, including all
the PC-based applications we have today.

The hybrid-bridge in the middle MIGHT be a PC, but is equally likely
to be something, say, Rabbit-based.

However, rather than simply passing the same xAP messages from one
side to another, it could process them, and take into account
state... thus leading IT to be the "rules engine".

With any decent volumes, a Rabbit-based device could hit a £100 price
point today. In the next couple of years, we'll see the power of
devices at that price point go up, and likewise the cost of devices
at that power point go down.

Such a device would be a FRACTION of the cost of a Homevision, and
compared to anything comparable would blow it out of the water.
