an example of a vault system I propose:
the user got 1TB drive to “give” to the network.
500gb are divided to all the test networks
500gb are the users choice to “gain most rewards” and “help vote” for the best test network
such voting will show us which inmplementation will make people participate quickly and which network can respond fastest and all the info we can get by having a regular testnet but this time we test mutliple testnets
in this way the maidsafe team can in parallel test lots of scenarios, like PtP PtC PtWhatever that have been suggested
