I could not agree more.

Let me add a few more lines of thought on this to go a little beyond the
dynamic ISP selection allowed by the unbundled model. In the past few
years the end-users gained extra power with systems that allow them to
play the role of connectivity providers (they were already a kind of
content providers with p2p). If we join to this the increasing
availability of open source tools and open systems, maybe we can picture
a brave new world.

Technically, this is not so difficult to do, and the prove if the
existence of companies like FON and Wisher, already mentioned before in
this mailing list. However, how BT, Virgin, T-mobile, ..., would see
this is a totally different story.
