The communities of the Aquarius phase are likely to be some of the most ‘wired’ communities of the 21st century, host to Ubiquitous Computing environments linked to the global Internet and supporting a vast spectrum of personal communications, entertainment, information, and hard data communication between the various supporting subsystems of colony infrastructures. Aquarius will set the pattern in IT for much of later TMP development, marine colony systems serving as proving grounds for architectures that will be employed, with progressively more advanced hardware, in the later Asgard phase and on the lunar and planetary surface settlements of the Avalon phase.
