RE: Re: Displays round the house - architecture...

["Ian Lowe" <ian@xxxxxxx>]

I can see what you are saying, but we have been through *exactly the
same*
series of developments before.

The concept last time started as a serial display, wound up into
rabbits,
PICs, TCP-IP, protocols, and promptly fell flat. This sounds very
familiar.

It's a simple set of problems:

Distributed == Intelligent Nodes == Expensive Nodes == High Entry
Barrier

Centralised == D.A.F. Nodes == CHEAP Nodes == More Participation

Personally, being a network bod by trade, I find TCP/IP very appealing.
My
"ultimate end goal" would use simple Ethernet, with off the shelf
hubs,
possibly running across a 10Mb network with a bridge out onto the
"real"
network of the house etc etc.

But realistically, as soon as I see the passion for IP, I think it's
basically doomed. Using TCP-IP seems to wipe out all of the low-end (ie
cheap) PICs, and takes you into ?50 module country, plus anoher healthy
chunk for the display..

Get some display systems working over D.A.F. Serial, you can add a
siteplayer interface on the front as a stepping stone...

PLEASE PLEASE PLEASE prove me wrong if you think I am, but *think* about
it
first guys, this has happened before.

Ian.
