By 'nothing between' I meant 'nothing that is worth mentioning in a newspaper article.' But you raise an interesting point, the entire wiretapping needs to handle a similar load as a large datacenter and should not impact the uptime, and therefore it should be quite an engineering challenge. So there should be documentation on the Google side, how to 'plug' it into a data center, which power requirements that stuff has, etc...
Which means that it's not something that Larry Page can just sneak into his datacenter without his squads and squads of Googlers never picking up on it, true.
