richms: How is it any different then not expecting sky to sort out sending it to more than one TV at the moment? All that needs to happen is definitive boundrys be drawn up on where each service will and will not support to, and then a market of lower tier integrators will spring up to help sort out the lower end houses that have traditionally not had any form of automation or structured cabling in them.
Hell, even the likes of harvey normal would love to get in on that cash cow.
I personally find it quite different to the Sky TV example. Your proposal does not address the complexity of inter-service-provider dependencies and boundaries; quality of service issues that will result from the first issue; ip addressing conflicts; the fact that there could be multiple network CPE in the home; routing; management of devices; etc. It is no-where near as straight forward as today's models as right now there is a single IP access to the home, not multiple. I don't think most integrators will be able to resolve this very easily as it is a big, messy problem.
I eagerly await to see how this will be resolved - we should see very soon with the Singapore NBN due to turn up first real RSPs and customers at in the very near future.
NB: I'm not particularly pro an L3 FTTH/NBN/Wholesale infrastructure either as it has huge drawbacks, so you could call me somewhat ambivilent. However I really do want to see the home networking issues resolved for an L2 model with multiple IP service providers.
