I will take a little different twist to this. Many countries have already done in Europe.... If your last mile, where control resides with a very few people, is regulated to be open, then everybody has access to it.
If you go back a few years, there was something called Bell Nexxia, which was a wholesale group separate from Bell retail. Bell Nexxia had no problem increasing sales, because it increased its profits. It didn't have a conflict of interest with its retail competitor. Regulation doesn't need to be wide; it needs to be focused. If you have that last mile open, everybody can use it, and it will grow.
