Toward sharing a single infrastructure

Our fifth poll has ended: how many infrastructures do we need for proper intermodal competition? The question was meant to be taken really in a very general sense, but focusing on access networks.
Possible answers went simply from 1 to 5 (or more). Here are the results, which are as interesting as you want them to be:

1. 48%
2. 8%
3. 24%
4. 4%
5. or more: 16%

If we go by the winner (48% voting for a single infrastructure), the conclusion could be: we only need one FTTH network; and let's start unbundling those mobile networks too! Obviously, we need some rules to make a monopoly work, however.
