RE: Re: Topic 4: Point to point acknowledgement in xAP messages

[Ian B]

I realise you are in the right ball park with your percentages but we must
not lose track of devices which are inherently serial but have an Ethernet
link to the rest of the world. I hope there will be lots of examples of
this
when the Rabbit 'bridge' goes into production. I certainly hope to use this
to Ethernet enable the devices I am working on.
